I am slowly building a "fun" e30 (was 325i) with a few go fast bits to do alot of street use and a little track day action, and have a few questions about brakes and weather or not a big brake upgrade is better compared to a 5 stud swap, (cost, easiness, wheels)
I currently have a set of rx7 brakes but i don't think there going to hack it.
We think I will be adding around 150ish kgs to the engine bay and easily doubling the horsepower (probably a lot more).
The main question I have is if I do the 5 lug swap will 330i e46 brakes be big enough? or would the 540i/750i 4 lug swap be a better option?
Also would love to here any other advice as well. Very new to this side of performance and I would like to be able to stop if I go a bit fast on the track.
Cheers
Sam
