+45 Offset on S14 for road racing? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Driftingcorners · 06-07-2011, 08:53 PM

Hey guys,

About to buy some RPF-1's for road racing. 17x9 +45. Want to run a 265/40/17 setup all around, so no hella flush shit for me! Will a +45 work or be too high? Also, as hypocritical as it sounds, how will this setup look....

Should I go for something lower than a 45...may have an option in the 30s...

TY guys

it should work in the rear, however, you will have clearance issues in the front with the strut/spring. If you have coilovers it won't even be close, you will need a MUCH lower offset for front and possibly for rear. Go for the 9" +22 up front and then use spacers as needed. I'm assuming you will want to dial in some negative camber for the front so you should not have to modify the front fenders very much, maybe a roll. Rear I would do a 17x9" +35 vs. +45

no good IMO. as said above, it'll interfere with the springs

I have a question, Why are you looking at that particular size and offset? Why not something that will actually work for your setup like stated above?

While running a 265 during road racing with low tire pressure, wouldn't it cause your tire to roll over on its self?

I'm thinking a 265 on a 17x10 or 10.5 20 ish would work best and not have as much rollover and still net you clearance. Also depends on what suspension you're running.

Any who, maybe pics will work best in explaining what I'm trying to say.

Don't do it. Please don't do it..

those wheels will narrow your track width, which will take away from grip/stability. Plus that wide of a tire will be wasted due to how narrow the rim is and allowing the side wall to flex so much.

you'd be ok, but handling might slightly be affected. a stock-ish offset will have the rim/tires sunk in, go with a lower offset or get spacers to bring the wheels outwards some more.
