5 Lug and Big Brake Kit

[Zambuzan]

If you PM me your email I can send you the installation instructions and parts list. That should answer a lot of questions.

Its basically the custom parts you need to run OEM parts from later models on your car. No suspension geometry changes or hacks. Only hubs/bearings and brake parts needed. Z4 hubs can be used on the rear as a cheaper alternative. Yea E30M3 = Pay to Play lol ask me how I know :p

You realize z4 hubs will push the wheel out like 15mm compared to stock e30, right? You're going to have some pokey offset in the rear lol. I wouldn't necessary call that no "geometry changes." But you're right, pay to play e30m3 would be the way to go...

I actually have the rear caliper brackets machined 2mm thinner to fit the Z4 hubs.

Any change in track width? I've seen similar kits and see they have an increase of 12-15mm in the front and somwhere around 2mm in the rear.

12mm in the front (from the E36 flange/bearing) and none in the rear if using E30M3 parts. Z4 parts would move it 2mm in.

Somewhat technical question for you . What’s the caliper piston area increase in this kit over stock e30 calipers ?

E36 M3 calipers have a 60 mm piston
540i rear calipers have 40 mm piston

Stock E30 is 48 mm front, 33 mm rear.

If you have a manual setup, this is a great first step towards functional brakes, at the cost of having to run 17s. Brake pedal effort is easily reduced by 50% or so.

I recommend 17's but people have fit 16's.

I've contacted you before
But just wondering, by any chance do you see a group buy for this in the future?
Or once they're gone that's it?
I ask because I only need the front setup
Hell if there's a group buy I'll buy a full set and fronts if I need to cover a slot lol
Thanks in advance
