Default Re: Back right tire locks up under hard braking?

Ask around your racer friends and see if someone can corner weight your car - just to see what it is, since you can't easily adjust it. You might find that the RF wheel is light, certainly with one driver and maybe also with a passenger. In my experience, a 100lb difference between LF and RF is possible and significant.

If you can get this measurement, you could consider installing one "lowering" spring cap on the RR. This is load up the RF and LR tires more. (In NASCAR, called "wedge") For purely braking performance, you would want the LF and RF (with driver) to weigh the same as the nose gets heavy under deceleration. Only if you are really really good at corners (I am not) you might sense that the car is very slightly different cornering left vs. right.

Instead of a lowering cap, you could also cut one thinner. It's an easy 2 minute job for anyone with a metal lathe. In fact, if Gen 2 and Gen 1 caps are same, I will include one, cut thinner, with the brakes for free as long as you send me back your old one. (I might have a Gen 2 cap, not sure.)
