Stock springs, and dampers, paired with Vorshlag camber plates. Car is set at -2.1*F/-1.6*R

I will upgrade to this setup in 2015 lol. I have dinan camber plates now and the wheels i posted! but haven't installed it yet. ill will moving to North Carolina in july. I need to find STX events.

If I was to do it again, I'd spec better dampers, a la Koni Yellows, etc. The car has always been under-damped for what I'm accustomed to. Otherwise, no complaints here. Vorshlag's plates were a great decision!

Just for reference, with an otherwise stock suspension, I was able to dial in -2.4* at full tilt with the Vorshlag's. Pulled it back a bit for a conservative starting point. If tire wear dictates, I'll set it up for more camber. The Hankook's clearly demonstrate the need for a lot of negative camber to operate effectively.

That's perfect!!! That is what im shooting for next, how do you like the 245 bfg rivals? I love my 225 square but I need to step it up to 245 now haha! These tires are by far one of the best street tires I had in ages!

Hey everyone, I'm looking to pick up 17" track tires and wheels. Since 245/40/17 wouldn't work well up front (stock 135i m sport), I'm looking at 225/45/17f and 245/40/17r. Would this be ok? As for the wheels, 17x8f and 17x8.5r? And what offset would be decent for visuals and leave enough room for track duty? I saw on the other wheel thread +45 rears, not sure about the fronts.

A few options for 17" wheels. For 225 / 245 staggered combo.

Apex ARC-8: 17x8.5 ET40 / 17x9.0 ET42 *
Team dynamics pro race 1.2: 17x8.0 ET40, 17x9.0 ET45.
Forgestar F14: 17x8.5, 17x9.0 in custom offsets.

I suggest getting tires such as Advan AD08R: 235/40/17 F, 245/40/17 R.
The rears will fit on 17x9.0 ET45 if you have -2.0 camber and not excessively dropped.
* If you have ET42 rear rims you may need to roll the fenders.

hi John, thx for the PM, I was just replying until I realized you replied here.

I'd like to go with the 225/245 combo for 17" (was looking at a cost-efficient set-up for my level of track driving, and staggered seems to be the only way to go on completely 100% stock suspension, 18" included).

I noticed you provided different offsets above, even at the same width (eg. 17x9 team dynamics ET45, but Apex ET42), why is this? and from what I've read online, nobody seems to have issues with 17" clearing the OEM 6 piston brembos.

I'm looking at going with 17x8 and 17x8.5. So from above, I can go with ET40 fronts. how about rears?
I've also found someone doing 17x8+40 245/40/17 Square, but not for track. Would this setup work?

I'm not looking to do ANY mods to the car as I'd like to see how it tracks with 100% stock suspension (2011 135i Msport). I have runflats, which I do not want to track with, so I'll be getting tires/wheels, and replacing pads/fluids before my first outing this season. I'll be looking at getting RS3s or equivalent.

(I don't want to go really wide on rears just yet, perhaps in the future as I improve on my driving. I had 275 RS3 rears on my 350z and I think it was overkill for me haha never broke the rears loose on the track, so clearly I'm not driving at that level yet. And Yes, I understand that the 350z has less torque than the 135i).

Many 17" wheels will clear the 135i brakes. My Moda 17x8 wheels from Tirerack had about 6mm from the caliper to the wheel barrel, but I consider this to be perfectly fine. The fitment was recommended by Tire rack. If you get wheels from the motorsport brands they are likely to have even better brake clearance, but not always guaranteed.

Ideally we would like to have rear offset of ET45 or more, but the wheels aren't commonly available. ET40 rear offset may be a limitation, since a Hankook RS-3 245/40/17 may be a very tight fit if your rear fenders are stock. At least you will need -2.0 degree rear camber as a starting point (set to maximum negative). Then assuming stock ride height it would probably not rub.

A couple of posts above, you can see the Kosei K4R wheels that are 17x8.0 ET42. It can be used. I personally prefer not to put a 245 rear tire on a 8" wide. After trying it I can say the grip is a noticeably more consistent on a wider rim, so 8.5" or 9" is preferable if you can get it.

I understand you like to try the car stock, but you will probably need revised wheel alignment if you want to fit the ET40 front and rear wheels. Since the front camber is not normally adjustable I suggest getting front camber plates in the first instance and set them up to for just enough camber to give good fender clearance. About 1~1.5 degrees front camber would give generous clearance for RS3 225/45/17 and the car will still have understeer, at least until the tires start to go off. I think wider rear rubber is an advantage in your situation because it will be able to handle the heat better and improve stability.

Thanks John. I guess I'd have to either stick with oem sized tires or get camber plates. Dammit haha I was trying to avoid all that this season.

[John_01]

The rear 245/40/17 is more likely to rub. The RS-3 225/45/17 on the front may fit ok, so you could try it first and see if the camber plates are needed or not from a fitment point of view. They way I see it, there isn't much point running completely stock camber if you intend to drive on a track. It will just damage the shoulder of the tire and not provide much grip.

[l2iceman]

Thanks John_01. It's odd that the 245/40/17 would be likely to rub when the oem rear size is 245-width as well - and the overall diameter is about 90mm shorter than OEM.

If I'm going to get camber plates up front, I may as well just get a set of BC coilovers, which come with camber adjustability up front. I'll be keeping stock height as I don't want to go lower due to the driveway in my condo.
