F80 ZCP 666M Tire Setup

iDriftYou · 05-19-2019, 01:51 PM

Hey Guys, I wanted to get your thoughts on my possible tire setup for an upcoming track day at Bimmerfest. I currently have the stock 265's up front with 10mm spacers, rears are 305/30/20 on stock 666m wheel without a spacer. I just purchased 285/30/20 sport cup 2's for the front and 305/30/20 sport cup 2's for the rear. The front is what is troubling me, I've seen people fit 305's up front on f80's and was wondering what are the chances of this setup up working out for the front with or without spacers? I'm lowered on KW HAS with factory EDC shocks. Factory tire is diameter for the front wheels is 26.3" and 10.7" width, 285/30/20 SC2's are 26.8 diameter and 11.4 width. Here is a pic of the current setup. Thanks in advance.

There was a long thread about someone fitting 275s up front on 666M and was rubbing, I doubt you can go any wider on the F80. F82 seems to have clearance but not on F80. Are you going to cut the wheel liners to avoid rubbing?

I don't mind heating them up with a heat gun and pushing them in, what I'm more worried about the clearance from the shock tower

Well I went ahead and got them put on, this setup will only work with 15mm spacers up front. I did heat and reshape the fender liners, but all I can say is WOW, the car feels like a go cart! Thanks for all your help guys! Here are pic's:

does it look like that before with stock tire width?? I didnt realize how close the tires are to the suspension components like that.

Not sure, that was my main concern as well! This is with the 285's up front.

Are you seeing any decreased performance with such a wide and aggressive tire setup?
