Looking for fitment advice on an E30 M3 with H&R race springs. I have a set of APEX ARC-8 wheels that are 17x8.5" ET20 that im trying to decide on tire size and determine whether or not I will need camber plates upfront. The tire size recommended is 215/40R17 but says may require some negative camber upfront depending on suspension setup. Since the H&Rs are so low but also pretty common I wanted to see if anyone else has experience fitting these or if there are other options

Hey guys, wondering if anyone has any insight on fittinf 17x10 et20s in the rear. I want to pull them off but my suspension set up is not very aggressive. I’m on IE3 springs and soon-to-be 80a bushings all around. I’m debating whether I should go with 12mm riser bushings or not (don’t wanna go with weld-in tabs). Currently, I have -2.5 degrees of rear camber with the Ie3s. I’m scared that if I go with the riser bushings, I will have problems with the fenders riding on the tire because the camber would probably increase to about -2 degrees or so (I’ve already rolled the fenders). I’m also not really willing to go with too much of a stretch, I’m thinking 245/40s?
if anyone has any insight, please let me know! This fitment game is stressful lol

Need some tire help please.

Bbs rs 16x7.5 et19 front and 16x8.5 et20 rear.

I bought 205/50s and 225/45 and they are huge and needs lots of rolling. Car is also dropped on H&R sports.

Looking to get get new tires. Any thoughts??

Car: 1988 325i convertible
Suspension: KW V3 coilovers
Wheel: BBS RS Reps 17x8.5 et15 all corners
Tire: 215/40/17 or possibly 225/40/17

Can someone confirm this will work without any rubbing? Do I need spacers??

[Rubenlopez101]

Can someone help me on a size 16X9 25 offset. Car is lowered on eiabach prokit and konis. Thanks in advanced!

Been doing a bunch of reading and think I've come to a decision, just need some verification/confirmation before I pull the trigger:

Early Model E30
Fortune Auto Coilovers
IRE 295 BBK

For consideration:
15x8.5 +25 (5-10mm spacer all around (Exact size TBD))

Will 225/45/15 fit or do I need 205/50/15?

Rear Fenders are pulled and front fenders are rolled. I'm not all too concerned about aesthetics/stance. Just trying to get as much grip as possible for future plans (Aiming for 450+ whp).

My concern with the 205 is that I'm essentially losing a good bit of surface contact. The 225/45 should be about the same height as the 205/50 but the shoulder will be an inch wider. I don't mind lifting the car .5-1" to clear the wider shoulder if it means an 2" of additional contact area.

Is it possible to get e34 basketweaves to fit on a e30?

With an 18mm 4x100 to 5x120 adapters they will be at an offset of +2, you can make it work with fender work and narrow tires but it will be really tight. They wont fit as is. The will fit pretty perfect if you do a fill and drill.

Is anyone else here running the new ground control full coil over kit and if so what wheels and tires are you running? I just installed the kit and took it to the track and it was awesome but I am still running on 16" redrilled wheels and conti street tires. Want to go to the widest tire I can am open to 15, 16 or 17's. I do like the Apex wheels but I know they will be heavier than say a slipstream. Yes I have tried searching but can't find my exact combo.

looking these

or these

Either with a Toyo R888R in as wide as I can go. Probably 225 square right?

The guy I bought the car from says the fenders are rolled front and back but I have no idea how much.

Thank you very much for the help!

Very noobie question here. I have an '87 coupe with 14' bottle caps. Tire size is 215/70 R14. I am looking to get an e30 sedan, also with 14' bottle caps. Those tires are 195/65 R14. Are these wheel/tire sets interchangeable? Thank you.

Yes. If you Google tire size calculator there are a few good ones that will give you max and min tire sizes for a given wheel size.
those will fit
