I have had my ls1 swapped e30 for the past year, took it to two track days and i've been trying to improve the brakes for a while.
I'm running garrets hydroboost relocation, but unfortunately i noticed under heavy breaking the firewall flexes like crazy. I added large fender washer to the inside of it where the bell crank bolt mount, but there was still flexing making the pedal soft.
I decided to add a brace to the whole thing, i first used a bar but it was still flexing, then i bought a gokart tie rod kit and now there is absolutely no flexing at all.
Consider that the flexing was much worst before my e46 m3 brake swap.
