Construction method (fully cast vs. flow formed / rotary forged vs. fully forged) is the quickest and easiest way to tell. Like the other poster mentioned, I'd trust a flow formed VMR wheel more than a regular cast VMR wheel. Smaller details, within same construction type: My experiences have been mixed - I've had Alufelgen flow formed wheels bend hours after leaving a shop driving on normal roads. I've had fully forged wheels get minor bends. I've had my cast OEM ZCP wheels take lots of beatings and get only minor bends after a while. Given that experience, I think even within the same manufacturing method there are varying levels of strength and quality. For example:

Apex wheels are light, relatively inexpensive, and street and track price. I have been using them for about 10 years on my E36M3 and 8 years on
My E90M3, all street driven. |

I am running EC7’s 18x9.5 square fitment with RE71 275/35 tires. Should I run a spacer on the rears? If so what size. This setup is for track use. Thanks.

Nothing says you can’t run a staggered tire setup on square wheels (or a square tire setup on staggered wheels). Lots of ways to skin this cat. The important thing is getting that wide wheel up front, 9.5-10.5 with the tire of your choice depending on what you want from the car. So many more choices in the rear but up front you have to stick to something under 26” tall if you go wider than stock or you start hitting stuff. for instance, 275/35 front and 275/40 rear is a nice stagger that takes advantage of the extra room for a bigger tire in back, if you decide you want more rear grip but are otherwise happy with square wheels

I am 100% committed to 17’s for track/fun tires but as soon as a top tire all-rounder summer tire is available in 295/30-18 I’m going back to 18’s with square 10.5’s

Why you say that? I would argue it's one of the best all-around Tires.

It’s molded at low depth to begin with and is lousy in real rain or cold, has lousy puncture resistance and wears too fast to retain hydroplane resistance for more than a coupe months of street driving. But otherwise it’s a fine street tire they are truly a treaded r-compound
Edit: derp I see now I was not clear I run 17’s on the street right now and would stick with them for track tires no matter what, tons of great track tires in 17’s for these cars, but if ps4s or comparable comes in 295/30 eventually I’m going back to 18’s That’s my favorite tire size for this car because short and wide and fits up front Edit 2 stop tempting me with the psc2. Stop it.

I have three track days on them and the rears are wearing amazingly. Only about 1/32 of wear. The front outer edges are destroyed while the inner tread has plenty of life. I am now experimenting with some setup changes to address that issue. I'm already at -3.3 camber which should be more than sufficient. Next step is stiffening the front sway bar and I will install the SPL links to correct roll center, bump steer, etc. Hopefully I get it figured out. If so, I think I can get a ton of track days out of these things. Despite their high initial price, they may turn out to be a decent value - plus I don't need to mess around with multiple sets of wheels. That being said, they have the best grip when new and fall off with heat cycles. Grip is still relatively solid after 3 track days, it just isn't at the level they started (pretty normal I guess). They aren't a super soft tire that wears rapidly. It is proving to be the opposite. They are wearing well. Now if you are comparing wear to a true street tire, I would say they will wear more quickly. However, I would expect to destroy most street tires on the track - plus they suck in that application. As far as rain... I don't care because I live in SoCal.

I love the look of the ZCP wheels but man where they heavy, and 19" wheels really could limit your size options when it came to diameter/rubbing issues. If I had a supercharged M3, I'd roll with 18x10 fronts/18x11 rears.

The smart move for weight dropping at a reasonable price is to run Apex 18s — might lose 5 lbs a wheel.
Tires can vary by 5 lbs in a given size in this size range. Michelin and Conti are among the lightest. |

Honestly, if you're looking to daily drive your car, then I would go with a squared 275 setup and call it a day. You can rotate your tires this way and get a bit more life out of them.

One way to get around the grip you're "leaving on the table" in the rear is a small 5-10mm spacer, if you feel like the rear-end can't take all the power you'd like to give on corner-exit with a 275 or 285 square setup for instance, adding some track width can help make up some of the difference.

The car was transformed with this, I can't stress this enough. You go with a 9.5-10" wide front with a 275 tire up front and the amount of mechanical grip is amazing. The same goes for the rear with a 11" wide and 295 outback. Last edited by Dave07997S; 03-08-2018 at 10:41 AM.. |
