Wheel offset + Coilovers

[BBVNSX]

I'm Planning to go with coilovers and more aggressive wheel offset (17x7.5 +34 F / 18x9.5 + 36 R) and have two questions for the specialists...:wink:

When you lower the car, because of the NSX suspension geometry, the wheels will tuck in. My question is, will this happen in the front and rear or only in the rear?

Does anyone here have an idea of how much the wheel will tuck in for each inch the car is lowered?

Thanks

I am not a specialist but had a recent experience regarding this same issue. I don't know the measurement your looking for but I will warn you. I have 20" in the rear and 19" in the front and car handles like a dream but, the camber in the rear is killing my tires at 5-6k miles. I have coil overs and will be raising the ride height another 1.5" so I can re-align and change the camber. The current setting is maxed out and I am burning $400 Pirelli P-Zero's in the rear. The fronts are fine and have normal wear. I put the 17" stock wheel and tire back on the car to take a look and no comparison the looks terrible now that I am used to seeing the big wheels and tires. Hopes this helps, I put roughly 6k on the car in 2 years and just replaced the rear tires at $800.

I don't want the wheels to stick past the fenders, and since I plan to upgrade to stoptech BBK in the future, this means I'll end with the equivalent of 17x7.5 +30 F and 18x9.5 +33 (rotor hats on stoptech are thicker than OEM: 4mm F / 2.8mm R).

What i need to know is the effect described here: http://www.nsxprime.com/forum/showt...p-Buy/page12?p=1696113&viewfull=1#post1696113 ,when going from OEM ride height to a lowered one (i plan to lower the car about 1,25"). and also if this same effect will happen on the front of the car...

thanks

I recall it will but not nearly to the same extent.
I'd need to look it up though.

i think you should be safe. your fronts should be flush, your rears should be about 10-15mm safe from poking out.

i am making these assumptions from comparing with the relatively well known safe/aggressive-ish specs of

17x8 +38
18x10 +45

that have run on many lowered nsxs, and then doing the comparison on the site below. punch in the numbers and compare with both your current (and future) setups.

running coilovers will let you lower the car even more == rear will tuck in more.

The setup you have listed will be just fine. In fact my car now is lowered just with Bilstein shocks and the rear im running a 18x9.5 +40 (so your setup in the rear would stick out 4mm more) and sits almost flush with the fenders. This look works really good because you are able to dial in the back to factory alignment specs, which will give it a meaner look. If you lowered the car about 1 -1.5 inches more you would notice the rear tends to start looking weaker, giving it a less aggressive look due to the camber. Some will never notice or even care, but to me it's night and day difference from every angle of the car. As for the front and rear camber questions. The rears will camber, but the front not so much.

Thanks very much for your replies!

Since i can't lower the car with the OEM suspension, yesterday i decided to do the inverse, so i used a jack to raise the car. I found that for every 10 mm i raised the front of the car, the top of the wheel next to the fender would protrude approximatly by 1mm. On the rear i found it to be 2mm for each 10 mm.

So for a very rough estimation i'm assuming that if i lower the car 30mm i can expect the front wheel to intrude ~3mm and the rear ~6mm, again this is a rough estimation... and i'm not sure about this... :redface:

Wish I had better angles to show you but these are my specs dropped preeeety low.

From what I am noticing only the rear tucks in. The camber in the front doesn't really get affected by being dropped.

18x8 +32
18x9 +20
