Hi all,

E30 pre (1987) can have 16x9 ET 20 on the rear without rolling fenders? Car is lowered with H&R sports.

Also, minimun tire width so that it won't be so streched on those rims should be at least 225/40?

Thanks,

Hello there fitment expert. I'm looking at a set with the following specs:

17x7.5 - Offset: +32

Late body style car, lowered on Ground Controls, camber plates, etc. Looking to run a 215/40.

What is the lowest offset I could pull off with only fender rolling? I'm not expecting anything too drastic, just want to push it out as far as possible without having to really beat up the bodywork.

As always thanks in advance.

How about 16" style 5s, et23. I want flush and I will be rolling the fenders. What size adapters to accomplish this? Thank you.

The smallest available, 18 or 20mm. Later add a small spacer to the rear, as your rolling allows (probably end up with 5mm to even out the stance).

Should bolt up without spacers. If you want to leave your fenders unrolled then you are limited to 205/40 F 225/35 R stretched fitment. With a bit of a roll in the rear 215/40 F 245/35 R is possible.

Hey Mystikal, I've got an 84 325e on H&R sport springs with Bilstein sport shocks and my summer wheels are in need of new rubber. Currently running the

15x7 et20 Racing Dynamics RG-P with 205/50-15 Azeni RT-215's the previous owner was using for the track

I'm trying to decide between a couple taller tire sizes
205/55-15
225/50-15

Primarily a street car, but will likely see autocross days every second or third weekend through the summer. In the 205/55 size I'm looking at the S-Drives or the Direzza DZ101. But it seems like 225/50 options have dwindled. What do you recommend?

Hey Mystikal, got a question about a 97 M3.

Running stock suspension, looking to fit some Roadstars 17x7.5 et41 up front and 17x9 et8 in back. OEM tire size was 225/45 front and 245/40 back.

I'm not huge into stretch, and I'd like to run as close to OEM tire size as possible. I've seen the SW thread with the guy running 215's on all 4 corners using a square set up of the 9" wheels. So I'm thinking 225/45 would fit in the front with the 7.5" wheels right? In the back I'm sure some rolling is called for, but how much of that OEM size will I be able to realize with fender rolling? Basically, is fender rolling enough for the rear, and how much do I need?

Looking forward to what you recommend, helped me out on a bunch of setups, much appreciated.

how would 205/50/17 fit on 17x8 wheels on an e30?

[bmoores]

Just ordered a set of XXR 521's - 16X8's with a 20mm offset. What is the ideal tire to use for these?

[stamar]

205/50/16 or 225/45/16 and base it on which gives you the better tires.

the 2nd size is for like your expensive summer track tires.

You're right, there's very little left in 15" summer tire choices. I'd recommend the S.drive for what you're looking for; it's a great tire all around.

It's absolutely impossible to fit those rear wheels on an E36 without stretch/camber/fenderpull/coilovers. Sorry!
