  • Q: Stock?  Ninjor 10 months ago

    Answer

    Can you run these at stock height? Might throw these on a week before my coilovers as my ball joints are bad.


    • A: These are NOT recommended for stock height vehicles.. Only lowered vehicles.

  • Q: Will I need this on rce yellows?   plowboy6602 2 years ago

    Answer

    My car is sitting on rce yellow springs which is right at a 1 inch drop. Will I need to correct my steering geometry or is it fine with the mild drop?


    • A: This would be a good addition to your setup. I recommend if for any cars that are lowered more than 0.5-0.75" lower than stock.


      Josh P. 2 years ago
    • A: Yes, some steering geometry correction would be required and this kit is specifically designed for a 1" drop so it would be an ideal combination.

  • Q: H.6 with Aluminum after market control arms!  sexwhirlpool29189 2 years ago

    Answer

    Hello! I have a 2001 H.6 Bean outback and was thinking if these here could fit with the set up I have. I recently purchased after market aluminium control arms that are about an inch longer than the OEM steel control arms recently fitted on until I bent the steel OEM control arms sliding into a curb. Last week I went to have my car aligned after putting the aluminum control arms on and the mechanics said that I in order to have a "correct" or "good" alignment I would need either longer tie rods with more threads, or I would need to not use the after market control arms I just invested in and just use the OEM steel control arms! Now I do not want to purchase a new set of control arms. I would love to be able to use these aluminum control arms with my car some how!!!! Would these help me out with the making the geometry of the suspension be "safe" or "correct" with the current aluminium control arms? Are these the same length as the OEM counter parts or longer? If these are not longer or if these to not have more threads than the OEM counter parts could you direct me to parts that do, please? Thank you for the help! I appreciate the time.


    • A: Hi Sexwhirlpool, The Whiteline roll center kit tie rod ends are nearly identical in length to the OE arms and would not be suited to resolve the alignment angle problem you described in your comments. I'm unaware of any kit's that would be suited to resolve your specific problem.

  • Q: bump steer kit  cgivette3643917665 2 years ago

    Answer

    Is there any difference between these black roll center kits and the old original color one's?


    • A: Hi cgivette, We have had a couple of different versions of the KCA313 (three I beleive) so I'm not sure exactly which original version you're referencing, but there was a change to the internal components of these kits to allow for a longer service life. There were also revisions to the retention method of the boots supplied.

  • Q: Whiteline Tie rod/ball joint kit.   95ej22 2 years ago

    Answer

    This kit is recommended for lowered Subaru's. I have a 2.5" lift (outback strut assembly swap) on my '95 legacy sedan, and will be replacing my rack and pinion soon, would increased front roll center geometry be good or bad in this type of situation?


    • A: As you mentioned, this kit is specifically designed to correct steering geometry changes on lowered vehicles (about 1"). The kit would not offer any performance advantages for a lifted vehicles, and would very likely cause some adverse steering/handling effects. I would not recommend installing this kit on a lifted vehicle.

  • Q: Will this product fit my JDM 1996 WRX (GC8)?  Koopsta 3 years ago

    Answer

    Will part number WHI KCA313 fit my JDM 1996 WRX (GC8)?


    • A: Yes, this product will fit the following chassis as mentioned. SUBARU IMPREZA GC SEDAN MY94-00 EXCL WRX & STI(4/1993-9/2000) (WILL FIT BOTH USDM & JDM GC MODELS)


      Jonathan @ Whiteline 3 years ago
  • Q: JDM fitment  Type 3 years ago

    Answer

    will this fit a jdm 1998 V4 sti type r. thanks


    • A: Hi Type, This kit is confirmed on the 1998 JDM STI, but I don't hve any specific fitment confirmation for the V4 type R. I would venture an educated guess that the tie-rod end'd and ball joint's were unchanged but some additional investigation may be warranted as this is a non-US spec vehicle.

  • Q: Tie rod ends  guest55c81419caae52f46098b9f9 3 years ago

    Answer

    Do you sell the tie rod ends separately? I have the whole set on my car but one of the tie rods is bent from an accident. Please let me know. Thank you


    • A: We do not sell tie rod ends separately.

  • Q: Would it be beneficial for a 1 to 1.5 inch drop?  evaradar 3 years ago

    Answer

    I have a 2009 Impreza 2.5i sedan, currently on OEM 2011 WRX struts and springs. I plan on getting an already custom fabricated 2013 OEM STi struts with RCE yellow springs, which will be a direct bolt on to my car. I was informed this drops the car 1 to 1.5 inches. Therefore, would this application be beneficial for that drop? Or would it require the car to be more than 2 inches of a drop?


    • A: This kit is designed for vehicles lowered about 1. At a one inch vehicle drop, the steering geometry would be near identical to factory original. This kit would still benefit your application more than not having it at all.


      Jonathan @ Whiteline 3 years ago
    • A: This kit is designed to alter the vehicle steering geometry close to stock on vehicles that are lowered about one inch. If your vehicle is at factory ride height then not only would you see no benefit in regards to the steering geometry correction, but it is possible that it will adversely affect the handling. I would not recommend installing this on a stock ride height vehicle.

  • Q: Stock replacement  Wilcox 3 years ago

    Answer

    Can these be used as a general upgrade if my stock tie rods and ball joints need replacement. Car has lots of bracing but stock suspension still. Just don't feel like using O.E stuff. I guess I am asking if they can be used on a car with stock ride height or even slightly lifted.


    • A: This kit is designed to alter the vehicle steering geometry close to stock on vehicles that are lowered about one inch. If your vehicle is at factory ride height then not only would you see no benefit in regards to the steering geometry correction, but it is possible that it will adversely affect the handling. I would not recommend installing this on a stock ride height vehicle.


      Jonathan @ Whiteline 3 years ago
    • A: This kit can be used as OEM replacements on a stock height car, but it is not recommended. The control arms will be pushed down by the extended ball joints and that can affect the steering.

  • Q: improvements with stock height?  vaporsti 3 years ago

    Answer

    I'm looking to buying these for the simple fact that both my tie rod end ball joint bushings are worn. What better to replace them with than aftermarket. however, I do see alot about how well this will work when the car is lowered. being stock height will i see any gains in handling? or will these simply just fix my leaky joints til I get lowered. thanks!


    • A: These will not have much benefit if any on a stock vehicle and are designed specifically for lowered vehicles that need a roll center correction.

  • Q: Retain Stock Conical shim?  ljluther 3 years ago

    Answer

    It does not specify that it comes with / doesn't come with the cone shaped shim for the ball joint. I would assume that it doesn't come with it, but it is still required, correct? I did not see it in the pictures anywhere


    • A: That is going to be for specified vehicles, if your vehicle originally does not use it is not needed.


      Stevens Henager 3 years ago
    • A: KCA313 includes all the items shown in the images above: Two replacement ball Joints, two replacement tie rod ends, (4) castle nuts, and installation instructions.

  • Q: How low ?  SubÉric 3 years ago

    Answer

    How low I have to be if i want exactly the same goemetri as stock?


    • A: Assuming I understand your question correctly, I would say this kit is warranted on vehicles lower than 1 inch from the factory spec. Thank you.


      tempemail55c523d5caae525b088b4bb3 3 years ago
    • A: This kit is designed for vehicles lowered about 1. At a one inch vehicle drop, the steering geometry would be almost identical to factory original.

  • Q: Eibach Springs  CESR 3 years ago

    Answer

    I will be getting some Eibach lowering springs which will drop my cars front end roughly by 1.4in, and the rear by 1.2in. Is it absolutely necessary that I upgrade to this kit or any similar kit? Or will my OEM tie rod ends/ball joints be sufficient?


    • A: This roll center kit is not necessary for lowered cars, but it is recommended and the lower the car is, the more beneficial this will be.


      Zach G. 3 years ago
  • Q: Compatible with Springs  stephen.whitmore8513277 4 years ago

    Answer

    Would the .8inch drop from the eibach spring kit be enough to substantiate this kit? I had asked previously about running this on a factory set up and it was not suggested. I live in a wintery area and I don't want the salt and snow to ruin a 2k$ set of coilovers so for now I was considering springs. Your thoughts?


  • Q: Negative Handling Attributes, Because of Stock Ride Height?   Froseph55 4 years ago

    Answer

    I wanted to install these tie rod ends along with Whiteline's anti lift kit. A modest 10-20 mm ride height drop is foreseen in a year’s time. Would this change have negative or positive effects on my car during this time when it has not been lowered yet? Thanks


    • A: Installing this kit with stock height will have very mild negative effects because the suspension geometry will be changed.

  • Q: Inner and Outer  sramnarain688044 5 years ago

    Answer

    Does this kit come with both inner and outer pieces?


    • A: Inner tie rods are not included with this kit, but outer tie rods and ball joints are included.


      Zach G. 5 years ago
    • A: what inner tie rods would you recommend besides OEM


      sramnarain688044 5 years ago
    • A: The OEM inner tie rods work very well and I would personally use an OEM equivalent inner tie rod. Unfortunately I don't have any suggestions for an aftermarket inner tie rod.

    Answer

    • A: yes it will run just fine no matter how its lowered, springs or coilovers.

  • Q: Race track  Totore 5 years ago

    Answer

    Which is better for race track ? Whiteline or GTSpec?


    • A: Whiteline puts a great emphasis on the improvement their parts make for both street and track use, but GTSpec is not necessarily a bad brand either. Whiteline uses different material, construction, and the drop of the kit is slightly different.

    Answer

    • A: You should still be able to install this kit at stock height, but it may not provide the same benefits that it would on a lowered car.

    Answer

    I have to replace my stock ball joints and tie rods on my 04 sti, I don't have aftermarket springs, I'm running stock. Would these be okay to install even though my car isn't lowered?


    • A: That should be no problem at all. And would be a good upgrade over the OEM units.

    • A: That should be OK. However your roll center will be a little off.

  • Q: Subaru Legacy 2010 2.5i Model  gborja888 6 years ago

    Answer

    May I know whether this fit Subaru Legacy 2010 2.5i model?


    • A: This kit will only fit Legacy models up to 2009 so it would not apply to your 2010. It appears that Whiteline does not make a roll center adjustment kit for the 2010+ Legacy models quite yet unfortunately.
