I've done some about as much searching online and general research, but cannot find an exact match with regards to offset/diameter with a set of H&R springs. I'm looking at going with a set of 19x8.5/9.5 Roderick RW-4's which are available in a 35M/45M front offset and 35/50M rear offset.
Question #1- I am certain I'll run the 50M in the rear, but since they don't offer a 40M for the front, would the 45M offset still work?
Question #2- With the H&R springs, will a 285/30 fit in the rear, or will I have to go 275/30? I don't want to drop to a 25 series tire b/c of lovely Louisiana roads.
Question #3- Also would a 245/35 up front fill the wheel wells better than a 235/35?

I know we are talking VERY minor differences in size and I know different mnufacturers sizes vary. If I go 235/285 I will go with Hankook Ventus V12, if I go with 235/35 or 245/35 up front and a 265/30 or 275/30 I would go with Sumitomo HTR ZIII. Had a friend that had Bridgestones, Dunlops, Vredesteins, Yoko's and Sumitomo's on an M5 and he said the Sumitomo's are the best out of the group overall which surpised me. I know what will fit at stock height, its just a question of what works in the offset, with the H&R's. Wheels are below...

You will be fine in the front, even with 245/35. I have 235/35 & regret not going 245/35 cuz I still have plenty of room left.

As for the rear, it will be at tight fit but you "might" get away with it if you find a tire with rounded sidewalls. 275/30 will work just fine if you want to be safe with H&R.

Regarding your wheel choice, they would look better if the spokes were straight. Just my opinion. Good luck!

I'll just go 245/275. I'd rather do that b/c at least I get the tires I want. I still MIGHT go with the Mandrus Velo in chrome, especially since they are specifically designed for MBZ. Roderick does offer the wheel in a straight spoke. I, for some reason, like the little twist. If I did get the Rodericks, I would get the spokes either polished, or custom painted. Not sure how I feel about the machined face. The Mandrus look amazing by themselves. I looked at pics online though and amjust not too sure...

Maybe they just look really good on a Z4 b/c they are WAY curvier and less angular.

Roswell

They do look good on the Z4, I agree! The Mandrus looks great too, good luck with ur choice! Are they expensive wheels (HRE or BBS category)?

No not at all. If you were desperate, you can get the set in 19's with Nexen tires for under $2K shipped...The Mandrus are about $700 a rim for the Velo in chrome, but its also a 3pc wheel. I think a set of the rodericks with some customwork would look good. Like if you were to paint the machined part in the same dark grey as the stock C63 wheel. Guess we will see... I figure too that if...aaahhhhheeemmmm....should I say WHEN I bend a rim (thank you city of New Orleans for your lovely streets) it won't cost nearly as much to replace.

The fronts will fit no problem the rears might work with the 285's given the high offsets.
