You should just barely be able to clear the stock fenders on an '87 with those wheels and tires.

I'm a newbie and have had no luck with searches. I'm looking for track wheels for my 325is in the original 14x6.5", ET30 size. Does anyone know of a source?

Hi Jay,

Thank you for making this thread, I'm sure it has helped many people make many different decisions.

Here's my situation: I've never been to a track before and I want to start going, I want to get serious/competitive about racing eventually, but for now I'm just concentrated on learning. I'm buying a set of TRM c1's 15x8et20 with the TC Kline S/A coilover set-up and hopefully vorshlag camber plates all for my 1990 325i 4dr. I'm having trouble deciding what tire size I should wrap the c1's in, or even what brand for that matter. I heard 225/45/15 should be good but I wanted to ask you since you seem to be very knowledgeable. Will this size be good? What would you recommend for a street/track car? This e30 is also my DD, so I would really like to get some ultra high-performance or just high-performance all season tires but I'm not sure which one to get. I want to spend somewhere around $80-$100 per tire... I hope you can whip something up for me!

Thanks for reading,
Darius

For a daily driver looks and speedometer/odometer accuracy are key, so stick with a proper diameter tire (24").

Those wheels were made extremely aggressive for the track crowd, so tire clearance is an issue. To run 225 tires, you'll need to roll the rear fenders. I recommend 225/50/15 BFG G-Force Sports, they're a great dual-purpose choice.

Hello,

Forgive me if this rim setting was already asked but the thread is 50+ pages long and i after reading about ten of them i havent found it

so here we go:

i want to install a set of BBS RM012 ET33 15X6.5 (keeping the stock lip)

The car: 1989 325i coupe on H&R Sport (1,3 inch front. 0.4 back), Bilstein Sport damper

first question, do i need to run spacers?

secondly should i fit 205/55/R15 or 205/50/R15 ?

this is my daily driver

Thank you for your help

Are you buying those RM's on kijiji?

[murcielago54]

Nah, i bought mine last autumn... from a guy on VWQuebec...

they looked pretty good and they were quite cheap...

[gervs]

There is a set on kijiji right now, i'm thinking of picking them up if we find out they fit lol.

[Mystikal]

You won't need spacers, but the wheels will be very sunken into the fenders without them. I'd recommend 15mm front and 20mm rear spacers for ideal fitment.

Either tire size is fine, but the 205/55 will provide a more accurate speedo and fill the wheelwells a lot better.

@ gervs: The RM looks pretty good on an E30 and BTW, is your 318is white?

@ mystical: Thank you very much

[gervs]

No, it's sunf*kd red lol. So pretty much red and pink.

And thanks Jay. Another question, if we were to use the spacers, do we need longer wheel lugs? Or the stock will still grip enough thread?

Yes, any spacer larger than 3mm will need longer bolts/studs.

[gervs]

Interesting. Can I get these at BMW?

[Mystikal]

Nope, aftermarket. H&R sells quality ones, but there's plenty of smaller companies too. Usually it's easiest to just buy from somewhere that sells the bolts with the spacers.

Hi, I have a 88 325is with konis all around and Ireland Stage 3 race springs with Bridgestone Potenza RE11s 205 50 15.
I wanted to see if these buddy club wheels in 15x7 with a 35 offset would fit on my car.
