Rear Ride Height: 23.75"

22/29 T Bars

Euromeister 7 and 9 x 17 wheels
215/45x17 and 255/40x17 tires

Will I have rubbing problems? Will I have camber choices?
here are 2 options, both are compared to 205/55 & 225/50 on Fuchs 7 & 8 x16

option 1: 215/45 & 245/40 x17

note that in this 17 option both front and rear are shorter than the existing 16s, the clearance between tire and fender at both ends is also greater. All around this is an easier fit that the 16s. Also keep in mind that there is considerable variation in tire physical dimensions. Here the 215 actually measures narrower in section width than the representative 205/55 x16, each on a 7, per Bridgestone's specs. The reason is that the /45 series sidewall bulges and flexes less than the /55

option 2: 215/45 & 255/40 x17

option 2 front is unchanged, the 255/40 x17, this tire is ~.1" taller than the 225/50 x16 it is compared to and also has ~3mm less room at the lip, this is generally not an issue. Torque loss is also up from a net loss of ~1.3 lb-ft in v1 to ~6.2 lb-ft in v2
