Features & Product Details

RallySport Direct carries a massive selection of quality suspension upgrades brought to you by Whiteline. 

On this page, you are looking at the Whiteline Subframe Locking Bolts. If your factory subframe locking bolts have become loose due to time or mileage, it can cause excessive movement and or noise under all driving conditions. The Whiteline units have been designed to lock down that subframe in place to remove any excessive movement under normal or high-performance driving conditions, and it helps transfer that energy to the wheels for improved handling, chassis rigidity, and overall performance. 




  • Designed to lock the rear subframe in place under hard driving
  • Improves handling performance
  • Simple to install

    Track focused 6 years ago
    4out of 5stars
    I bought these primarily to check if there was substantial movement within the sub-frame - i.e. an experiment. While not immediately noticeable they do add a level of harshness to a daily driver that I personally would not accept, it is by no means night/day transformation - but the same also applies to the effect they have. If the car was track-only I can see how they would that last 2% to an already stiff setup and therefore be a benefit. To Whiteline's credit - as with all their products - it 'does exactly what it says on the box'.

    Not for Permanent Use 6 years ago
    0out of 5stars
    According to the Whiteline insert that came in the package, these are not to be used permanently, and should be removed after every racing event. I found this odd, as the Kartboy ones say they can be installed and left in the car for everyday driving. I ended up selling these and going with the Kartboy Locking Bolts as they specifically state they can be used all the time.

    2003 RS needs a tap! 7 years ago
    5out of 5stars
    the holes on my 03 RS were too small. i believe they were an M10x 1.25. these bolts are m12 x 1.25. didnt even need to drill it just ran a tap through it and torqued them down. driveline feels much more secure to the body! a bit more noise, sounds like the diff, but not too much.

    Tight back end 7 years ago
    5out of 5stars
    I didn’t expect to feel a huge difference in handling from installing 2 bolts, but the change noticeable. It has been a while since I installed these, but I remember feeling much more confidence and feeling much more connected with the rear. I highly recommend them!

    Noticeable rear-end difference 9 years ago
    5out of 5stars
    I had these installed by Andrewtech while my car was in getting an exhaust leak fixed up, so I cant comment on the ease of installation. What I can say is that they made a noticeable handling difference, which cost less than a tank of gas. I have them installed on my OBS along with fender cowl stays, a front strut tower brace, and an upgraded rear sway bar. They make the rear end feel very planted and combined with my other items make steering very “point & go”. It was especially noticeable during RallyX.

    • Q: materials  WinterBorn4 years ago

      the description for materials is 'steel'. What steel is it? Stainless? I am trying to find a stainless option for the bottom of my car as all other options are Zinc coated or black oxide coated bolts that will rust after one or two winters in the North East.
