Hi folks,
Many on this forum have noted they’ve installed
Square 264 (or 313) rims with success. But when I’ve searched around, there doesn’t seem to be a ton of photos/specifics – at least in comparison to Apex and VMR installations.
So just for reference, here's my (no-rub) setup and experience… for what it’s worth…
Suspension Setup
Rims, Tires and Spacers- 4x 18x8.5 ET52 Style 264 rims
- 4x 245/35 R18 Bridgestone RE050A RFT tires
- 4x 10mm hub-centric spacers from Burger Motorsports
Alignment- Front:
-2.2° negative camber, 1/32" toe-in per side, 7° caster
- Rear:
-1.8° negative camber, 1/16" toe-in per side
Ride Height- After installing the suspension parts listed above, I measured the following average drop in ride height as compared to the ZSP sport suspension with ~70K miles:
- Front: 9 mm drop
- Rear: 15 mm drop
- The Dinan camber plates are ~6.5 mm thick and add to the stack height of the front suspension
- This implies that the BMW Performance Suspension actually drops the suspension height by an average of 15 mm, more than the 10 mm per BMW’s product specifications
- Visually the drop looks pretty even front to back, at least to my eyes
Clearance- The fenders are stock, with no rolling/pulling
- The car has been driven over a variety of roads and conditions and there doesn’t appear to be any rub
- Front:
- Visually it looks extremely close from the tire to the outside edge of the fender, I'm kinda amazed there isn't rub
- Can’t imagine fitting any wider tire, at that camber angle
- Clearance between the front rim & tire to the strut is somewhere between 1/8” and 1/4" (i.e. ~5 mm) - measured using the feel blindly and guess technique
- Rear:
- At the beginning, I had 12 mm spacers in the rear but they rubbed under conditions of heavy suspension compression
- Switched to 10 mm in the rear, same as the fronts
- No problem since
Driving Impressions- Steering feel comes across as having a bit more stiction
- No perceptible change in ride quality
- Understeer is significantly reduced, but not eliminated
- Don’t know how much is due to wider front rims/tires, or increased camber
- Really the big change is that you can get the nose to point in more quickly, thus greatly increases confidence (at least for me)
There you have it.
Karl.
