I am thinking of running Enkei RPF1 15x7 ET 35 (they are also available in ET 41) on my M30 89 vert running M3 springs. I expect to run a 225/50/15 tire. I am trying to decide on spacer thickness and am guessing 10 mm front and back putting the ET at 25. Would this plan work well? Maybe it would it be better to go a little wider in the rear? I don't want to roll my fenders. What do you think?

10mm spacers won't have a proper hubcentric lip. Get the 41 offset version, then run 15mm spacers to get the clearance you need for 225s.

I'm thinking of getting the enkei rpf1 in 15x7 too. Just don't know which offset, the ET 35 or ET41. Or which spacer thickness to get. I plan on going with 205/60/15 tires. But if I can go 225/50/15 without rubbing, I would go that route. Bearmw, have you upgraded your wheels yet? Did you have to roll your fenders?

I am the chart, sadly. Those wheels should bolt up to an E30 fine, but front strut clearance will be minimal. B15 Sentra is 66mm center bore and E30 is 57mm so you'll need rings. Related note here's my GF's Spec-V:

nice pic...Rings? I'm guessing to make up the difference from 66.1 to 57.1 in the center bore? Would I find those at any tire store, or do you have a reccomendation? And since they're gonna start out as winter wheels, clearance issues are not good; would you reccomend a spacer in front for those wheels on an e30? If so what size? If it matters, car is a 1985 eta (prod. 4/85) and has bilstein HD's, stock springs and fenders. Thanks

Just found a deal 15x8 steelies et -12. Its already got skinny 195/45 tires so I would need larger tires.
But, do I need spacers to fit wheels.

[Aerton]

Tires are too large to work with 16x9s, unfortunately. Maybe with absolute fender hacking but otherwise...nope. Sorry.

Thank you!

I should just read this entire thread to find the answer to my questions...

Im on kw v2's

* 3-piece Schmidt Revolution Modern Line wheels
* 16x9
* Staggered ET 21 Front, ET 8 Rear
* Toyo Proxes T1-S 215-40-16 all around.

[gnarlycreature]

By The way its on an 85 325e. I hit the front brakes.

As far as the chart idea, I agree it would be a good idea.
I have not read the whole thread but I have to believe that certain wheels have been discussed before. Weaves, euro weaves, ronal ls, etc.

I'm currently riding on BBS RX's with 25mm spacers all around. Wheels are 16x7 et35, with 205/50 tires. I'm looking to possibly buy SSR Professor MS1R wheels and have a lot of choices to make as far as size and offset go. I would like to go for 17x7.5 and 17x8.5. Currently my fronts outside fill the arches just right. I need the spacers up front for the BBK (massive race kit) and the coilovers I'm running. In the rear I could possibly get away with a 10mm spacer with the current wheels, but they tuck about an inch more than I'd want. So do these values look way off:

front: 16X7 et10 becomes 17x7.5 et10 with 225/40 R17? Can run 4° of camber. If the wheels do not clear the BBK as is I may still use a spacer to get to this offset.
rears: 16x7 et10 becomes 17x8.5 et10? or et5? with 245/40? that way I use some space in the wheel well (about 20mm of space right now) and the other half fills up the wheel arches?

Can I trust the BBS and SSR offsets matching up? Just don't want to end up with a ton of poke or still have to run huge spacers.

+41 with 15mm spacers all around would fit 225/50 nicely. 205/60 is too tall.

Yes, centering rings. Local wheel/tire shops should have a selection, otherwise Discount Tire Direct and Tirerack with both (grudgingly) sell you just the rings.

Cheap universal 5mm front spacer is enough, you may even get to use your stock bolts depending on the wheel design.

-12 will be poking way out on all 4 corners. You'd need the 195/45s just for clearance, but the load rating is dangerously low.

Overall, those don't "fit" E30s.

10-12mm front spacers.

No 225/40 tires worth buying. Not sure what you mean by "becomes" as that would suggest spacer adjustments but you name a different set of wheels.

Just starting clean, I'd suggest +40 F +28 R. Leaves you lots of space for spacers up front and will sit the rears in a good spot for wide tires. 215/40 F 245/35 R (or substitute 235/40 for more choices).

[EclipseMTL]

Alrighty, since the BBS thread gets no action, I'll post this here =]

Okay, stupid question. I bought a set of these BBS'es, and was wondering a few things about them.


5x120, et11, 7x14. With an adapter for 4x100, would it even be worth running on an e30? It'd be +9 for the offset with an 20mm adapter correct? Would that be okay with a 7" wheel?

+41 with 15mm spacers all around would fit 225/50 nicely. 205/60 is too tall.

Just for a point of record, I am now running 225/60/14 (approx. .65" taller overall diameter than stock, and almost the same height as the 205/60/15 which is .05" taller than that) on stock bottle caps (I believe they are 35mm offset) with 15mm spacers as my street tires. They work great (my fenders are slightly rolled at all four corners) with just slight contact in the front fender liners when turning sharply at parking lot speeds. These tall sidewalls make the car ride great, which is an accomplishment with the stiff strack suspension and unpadded race seats. I also think it looks cool as hell with stock wheels and fenders full of rubber. Not the best handling setup, but with track alignment it does ok and it's a great way to have a car set up for track events but still ride well on the street! Rockin it old school with "wide 60's" (no I did not mount them with raised white letters out).
