jt1 Posted September 18, 2009 Share Posted September 18, 2009 It's close, it depends on your ride height and suspension travel. I have used 16x8 with +12 offset, and 245/45/16 tires on my car. With 275 rear springs and 5 1/2" ride height at the rear of the rockers, I had only very minimal rub, but any lower would have rubbed badly. There is also some variance in different tires of the same size, so that is also a factor. With the zero offset on the rear, you're going to have to stay pretty close to stock height to prevent any rubbing. I also rolled the lips on my rear fenders pretty heavily. Lots of variables, no set answer. jt Quote Link to comment Share on other sites More sharing options...
Bahraini240z Posted September 19, 2009 Author Share Posted September 19, 2009 thanks for the reply... I'm thinking of running 205/45/16 at te rear so I can reduce any chance of rubbing, not sure if it can handle an inch drop tho! Quote Link to comment Share on other sites More sharing options...
jt1 Posted September 20, 2009 Share Posted September 20, 2009 You might try reading thru the Rota wheel 16x8 thread. There was a good bit of discussion about what tire sizes would work. jt Quote Link to comment Share on other sites More sharing options...
310z Posted September 21, 2009 Share Posted September 21, 2009 These are BBS 16x8 - 0 offset with Bridgestone 225-50-16. The lips are rolled in front and I ground the rear lips to the spot welds. The stock front valence was not usable, as when the tires were turned they would be 0.030 in. from touching the valence. The valence shown on the car works fine. The front wheels have a 3/8 in. spacer used for caliper clearence not tire clearence. 225-45-16 would fit my car fine with either valence. I have struts, not coil overs. Everything is close but nothing rubs under any condition. Be careful with tire brands they are not all what they say they are. The TireRack.com has great information online about each tire under tire specs. You can see the measurement and variations amoung like size tires.

Bahraini240z Posted September 26, 2009 Author Share Posted September 26, 2009 thanx... those BBSs look sweet... I believe 225/45 would seat them better Quote Link to comment Share on other sites More sharing options...
batou Posted September 27, 2009 Share Posted September 27, 2009 310z, Is that stock ride height or do you have lowering springs? Quote Link to comment Share on other sites More sharing options...
310z Posted September 27, 2009 Share Posted September 27, 2009 310z, Is that stock ride height or do you have lowering springs? I purchased the springs 23 years ago. The car has been on jackstands most of the past 23 years until I finished a bare metal restoration that I finished 4-23-09 just in time to get to the MSA show. The springs are Tokico touring springs, (that stated like most preformance springs) they will lower the car 1 to 1.5 in. As I recall the car was a full 1.5 in. lower after first installing the springs. Then I realized that camber kits were a nessary part of the lowering process.

piston Posted September 28, 2009 Share Posted September 28, 2009 that is one clean z. i say put those fender mirrors on the fender!!! Quote Link to comment Share on other sites More sharing options...
310z Posted September 28, 2009 Share Posted September 28, 2009 that is one clean z. i say put those fender mirrors on the fender!!! Then it would look like all the others. Wanted to do something different. Something people don't see at every show. These are the mirrors American cars should have gotten. In the place American mirrors are placed, on the doors. They look great on the fenders also. Thanks for the complment and your opinion. Quote Link to comment Share on other sites More sharing options...

310z Posted October 2, 2009 Share Posted October 2, 2009 Off-topic, but nice subwoofer setup. I am going to do the same here shortly, though with a single, sealed 8 or 10-in. Well as this page has gone off topic I will give more on the subs. I was going to use a sealed box at first. Then a friend from Custom Works called Polk Auido and told them were the box would go and what we were working with. The folks at Polk said you already have a sub enclosier (the spair tire well). If you try to seal it, it wont work. So porting the box was the best option. Polk informed us of exactly how long to make the tubes and what diameter. The ported encloiser also produces more volume per watt whish makes the system more efficent, so I have read. There does need to be damping materal placed on the walls of the spair tire well, see pictures, a Dynamat product and it is expensive. But it does sound great and it is easer to build than a sealed box in that spot for the Z. Quote Link to comment Share on other sites More sharing options...
