TR Motorsport MT1 wheels
18" diameter x9.5 " wide
Offset: 35mm Backspacing: 6.73"
 Bolt Pattern: 5-120
Rec. Tire Size:255/40-18
Weight: 19.0lbs.


Bought with used Kumho v710 285-30-18.

Wheel/Tire combo weighs 42.5 lbs on digital bathroom scale.

Street set weighs 52.5 lbs rear (OEM CSL wheels with 265/35/19) and 49 lbs front (OEM CSL wheels with 245/35/19). Bridgestone Potenza RE050A Max Performance Summer tire. That's a pretty substantial weight loss from unsprung weight.

Also the track set overall diameter is almost 2 inches less and that acts like a higher numerical gear ratio. So there are tons of benefits from this combo. Let's hope it doesn't rub.

Getting alignment tomorrow because I have no idea where its set too. Feels alright on the street though. Gonna try to get camber to -2.5 front and -1.5 rear, with

 zero toe front and back.

First time I have noticed sway bar is 3 way adjustable. I think its a Dinan. I also think I should move it to the stiffest setting (closet to the front of the car):

Eibach springs. Not sure which model.  M3 guys measure distance between wheel center cap and top of wheel arch. Most hard core guys are about 13 inches.
This combo is currently 14 inches rear and 13.75 front.

 There is over a 1.5 inch difference in tire height between rears.

265/35/19's = 26.3 " tall

245/35/19 = 25.8" tall

285/30/18 = 24.8" tall

 

245 on left, 285 in middle, 265 on right:

 

Wheels need to be pushed out....Need to get rear spacers (10mm?) and longer wheel studs:
