R33 Front Arm Setup?

[Savtraxx]

This is my first car and I'm looking at the front upper control arms ( I think) and they are about 5cm from touching my tire... For now it has stock. 14" wheels , I'm putting 18" on it soon , how will it work??

Doesn't matter how big the diameter of the wheel itself is, the outside rolling diameter of the trye shouldn't change by more than a few percent. So, your 18" wheel and tyre should be almost exactly the same diameter from rubber to rubber as the existing ones. If you get wider wheel and tyres than the existing ones, (and of course you will), then the edges of the tyres will move inwards and/or outwards from their existing positions. What actually happens to the inside and outside edges of the tyres will depend on the offset of the wheels. Correctly choosing the rigth width and offset is the whole aim of putting bigger wheels and tyres on, so you don't interfere with the suspension or rub on the outer or inner guards, etc.

There is a whole thread on here about what wheel sizes and offsets fit R33s. Go have a look and read, and if you don't understand offsets and so on, the google them up and draw some pictures of what you think is happening until you do understand it, then you will be equipped to choose.

Cheers! Just hoping these wheels will fit , they're weds sa-60m 18 , 10" wide , $500 with tires off a mate

if its only rears and you got the +36 offset then yeah they should fit with a roll, if they are the +20 offset then hmmm I doubt it...

thats the only two sizes the 18x10s come in for that rim...

[Savtraxx]

They are +46 , will this work?

[75coupe]

either they are heaps old versions of the weds sa-60m rim or your wrong as they only come in +20 or +36 as far the interweb specs say

+46 - I dont think they will fit

[75coupe]

hmmm +46 maybe...

your better off asking one of the offset gurus on these forums tbh...
