Features & Product Details

These adjustable units are manufactured using state of the art machining techniques. These upper mounts feature a design that is unique to the market and have set a new standard for which others will be measure against.

The unique design allows easy adjustment with fixed reference points from left to right. You either add one, or remove one. The settings will be the same on both sides. No longer do you have to measure and clamp both sides to get it perfect.

The pillow ball bearings are custom made and have been tested to withstand the abuse of off road racing and rally competitions. The tolerances are so tight that there are no clunking sounds that are common in other pillow ball bearings.

This work on both the GC and GD chassis Imprezas. The mounting holes are marked for the side/chassis you are looking to install the mount on. There are holes for the GC left and right and the same for the GD.

All parts are made using state of the art 5-axis CNC machining out of T6-6061 aluminum, and use graphite impregnated bushings. The bolt holes are made from a technique called "thread forming" which is much superior to the typical cutting tap that others use. It creates a smooth thread that has no sharp points which means the chance of the adjustment bolts seizing and jamming on the burrs is significantly reduced. These will fit the OEM front struts/shocks as well as any coilover that utilizes a M12x1.25 thread pitch for the top hat bolt.

Mooresport Street Adjustable Front Upper Mounts ( Part Number: MSISUB02-18-001)
Awesome product that will help on the track 1 year ago
5out of 5stars

I finally got around to installing these on my ISC N1 coilovers today and they are great quality. They won't creep on adjustments like the stock ISC top hats did on me. the threads are very smooth and the nice looking gold bolts that they include thread on all the way by hand. I also like how they use bolts that thread down into the top hat rather than studs sticking up through the strut tower. looks much better in my opinion.

Replaced my rusted coilovers with Bilstein B14 47-101791. Had alignment issues and decided to get this item to correct the problem. Perfect fit for my Bilsteins.

Easy. Very Quality 3 years ago
5out of 5stars

Impressed me with the machining. Threads are very smooth. Bolts finger tighten right to the end. Solid bearing installed with snap ring- plenty of material surrounding everything lending them a burly solid appearance/feel. Does lift your car, 3/4 inch higher than stock tophats. Steering feels more solid when loaded during sharper uphil turns where Gforces are greatest.. Seems to create consistant lateral tire loading between inside and outside tire. Can feel sidewall flex during turn transitions under acceleration. Adjustment is simple, dissconnect sway, unload suspention, loosen bolts on tophat (2) and slide top of strut where you want it. The indexed camber adjustment locations made symetrical adjustments simple. Makes it easy to change it up for whatever the driving goal.

Very good product. 6 years ago

Extremely high quality. Very high range of adjustments. Coming from WL Com-C, I was ableto achieve additional positive castor (high 4 degrrees). Please note, this is not a longterm review.

  • Q: Camber Range   brettklynn477741 year ago

    These will be used on a street car that will see some Autocross time. I want to make sure these can support Negative Camber of less than 2 degrees to save on tire wear on off season Can these adjust down to the 1.5 deg neg camber on a GD?
    • 0 of 0 people found the following answer helpful

      A:  1.5 degrees of negative camber is easily obtainable with the top hats at any streetable ride height.

  • Q: Negative camber - stock WRX struts  ferrettank3 years ago

    Hi, What is the max negative camber I can get out of stock WRX struts with this set up?
    • 0 of 0 people found the following answer helpful

      A:  Camber range is approximately .2 degrees per adjustment hole. Range varies depending on ride height, castor settings, model year, shock manufacturer as well as lower camber bolt position (or camber washer). Camber range can be as little as 2.0 degrees in worst case, and upwards of 4 degrees in others.

  • Q: Fitment  Seth Hawkins3 years ago

    Will these work with the Tein Street Flex coilovers on a 2015 BRZ? Also, are they compatible with the Tein EDFC system?
    • 0 of 0 people found the following answer helpful

      A:  These mounts have not been tested with Tein Street Flex coilovers, but they likely will not be compatible. If they happen to fit the Street Flex coilovers, then the EDFC motors should work with them.

  • Q: Fitment with Tokico D-Specs  Frostysaurus4 years ago

    I have Tokico D-Spec struts, which I'm pretty sure have an M14*1.5 thread for the top hat bolt. I've seen people on other forums fit MSI plates on the D-Specs. Will these plates fit my struts?
    • 1 of 1 people found the following answer helpful

      A:  The top nut included with these plates would not be correct for your struts, but the KW specific mounts should work for you because they are M14x1.5.
