mchong75 Posted November 11, 2009 Share Posted November 11, 2009 Hey everyone The more I search and read over different wheel width and tire measurements, the more I’m confused. I have the opportunity to buy some BBS RS 16x8 by 11 offset. My 76 280z will be lowered by using Tokico HP shocks with 1†lowering springs. Is 11 too much? Should I pass this up and look for a 0 offset wheels? Quote Link to comment Share on other sites More sharing options...
310z Posted November 12, 2009 Share Posted November 12, 2009 Hey everyone The more I search and read over different wheel width and tire measurements, the more I’m confused. I have the opportunity to buy some BBS RS 16x8 by 11 offset. My 76 280z will be lowered by using Tokico HP shocks with 1” lowering springs. Is 11 too much? Should I pass this up and look for a 0 offset wheels? The car is lowered 1 to 1.5 in. These are BBS 16x8 0- offset with Bridgestone 225-50-16. They fit the car perfectly with the work I have done. With the stock lower front valence they did not fit. When the wheels were turned the tire was 0.30 in. from rubbing and that is why the air dam that you see got installed. There is a 3/8 in. spacer on the fronts to allow for caliper clearence and of course that did play into the clearence issue. With anything other than the stock lower valence they work. The lips are rolled but that does not appear to come into play. The rears fit perfectly also but there has been work in this area too. On the inside at the stock strut tower spring perch there is 1/4 inch clearence. The rear fender lips have been ground to the spot welds, this allows for full suspension travel without any rubbing although it is a 1/4 in. from touching the ground lip. I have read were guys claim to be running larger tire sizes and wheels or different off sets in a stock wheel well with stock suspension. However, they usually also state that it only rubs when I do "______ " add your own word. Well, that means they do not fit. Rubbing is not fitting, rubbing is a problem. So, tire size and availability comes into play. 225-45-16 will fit without a problem with a 0- off set wheel. So if you choose that size tire and off set your problem is solved. However, there are only three tire manufacters making a 225-45-16 and if what they make does not work for you or they stop making it, then you are out of luck and back to 225-50-16 and there is lots of availability in that size. Your question is, will an off set of 11 work. You do not say if that off set is - or + and I do not think it matters beacuse as close as my tollarances are with a 0- off set, an off set of 11 in either direction will not fit. Good luck, I put a lot of work into making a 16x8 in. 0- offset wheel fit into a stock appearing wheel well. Quote Link to comment Share on other sites More sharing options...
310z Posted November 12, 2009 Share Posted November 12, 2009 If you look closley at this picture you can see how I clearanced the rear lip right out to the spot welds. It appears that there is room for a larger tire wheel combination. But IRS when traveling up ward also travels slighty outward as the "A" arm becomes level with the pivet point.. So all these issues need to be looked at prior to bolting on a wheel and saying it fits. The picture should blow up if you click on it.
