So i have recently purchased an 89 cab with 75k miles... All original, etc.... I have ordered and received some brand new wheels from Rotiform LHR wheels.... They are 18x8.5 fronts and 18x10 for the rears.... My question is what is the best way to lower the car correctly and anyone have any suggestions as to what tire sizes to install based on specs?? I want it to have the proper stance yet also the right tire sizes.... These are the wheels and the Carrera.... Bronze matt finish with Bronze Gloss lips.....
You lower it by reindexing the rear torsion bars, and screwing down the adjuster in front.
Overall problem you're going to have is that you'll completely destroy any semblance of ride with an 18" wheel on this generation of 911. You'll likely end up with a 225 front, which will require fender rolling; and a 265 in back, which may lead to paint burn if you lower the rear too much. Trust you got known, workable offsets.
Welcome. You want to put 18 x 10's on AND lower it?
Please get rid of the 964 wheels, but man, start slow....find some middle ground like some 16" x 7&8 Fuchs with proper offsets. Your car was not made for 18's.
I have my original 6 and 7x16 with 3mm up front and a 12mm spacer in the back. Just barely squeezes the tire/wheel between the fender and the 930 calipers. Going 18" is just stupid. Honestly I think the OP was spam generated by a local ricer shop.
Against what seems to everyones wishes I went ahead and installed the 18 inch rotiform wheels.... I don't have one regret except they look amazing... Had the car lowered to euro spec and NO rubbing at all only turns....went with 225/40/18 for fronts and 255/35/18 for rears... I have to say that the rotiforms are much much lighter than the stock 17 inch cup wheels.... also redid the whole speaker system with arc audio components and under the seat rockford sub and arc audio amp.... Loud and crisp and clear>>>>
Welcome back. Sorry about the less than warm welcome we originally gave you. It was just odd that you posted what looked like spam and then never came back.
Most important is that you're happy with the end result.
And as the Cup 1s were not OE on a torsion bar car, they have always been an extremely poor choice as an "update" on this generation. If you had the chance to drive the car with the stock 16" sizes, you'd quickly come to understand the relationship between sidewall height and overall spring rate.

Thank you guys for the compliments. Don't get me wrong is like to purchase a set of fuchs to also have to put on. Just a timeless design and look. So if anyone has a nice set I'm here...

Gotta say that one of me favorite features when driving my '88 cab (with factory 16" Fuchs) is how well it handles without jarring my teeth out - especially on California's crappy roads.
