What is the maximum brake size that will fit under a 17" wheel? I know offset is also important but as a general rule, for example would a 345mm brembo conversion fit under a 17".

The reason I ask this is im seriously considering chopping the 18's in for 17's function over form reasons.

I would say no. K sport 356mm require some 18" depending on style or above.

Depends on the size and positioning of the calipers I guess....

 

There's not much difference in dropping the extra inch diameter - but the caliper sits close to the edge of the wheel already, then anything can matter!! Just out of interest why exactly do you want to switch to 17 inch rims? IMO 18s are the optimum size for a 300zx - 19s are nice but not practical or economical when it comes to tyre replacement (if you are fussy about premium brands like me) - and 17s don't really improve on ride quality over 18s....

Should fit, depends on style though. Trial fit before you commit

I was looking at using a set of R33 GTR alloys, for three main reasons.

They look good and they are a cheap quality lightweight wheel.

17" tyres are cheaper esp as the rears will be narrower mine are 265/30/18r high quality and or road legal slicks are expensive in those sizes.

Higher profile allowing a bit more bump allowance the 18s can be a bit harsh, also the higher profiles a bit more motorsport looking rather than mcdonalds.

That's what I was thinking, ive asked the same question over at the skyline club aswel as its those wheels I want and a lot of them have bigger brakes.

the r33 17's are not that light ...

In comparison to the large chunks of battle ship bolted to my car currently lol

compared to other 17's, should be able to get some rays for not much money, even rota's are lighter from a quick bit of research I did

Hem I think more research on my part is required, I found some one with them on a skyline and 340 ish mm discs and ap calipers there was literally a fag paper clearance.
