Tire Rubbing

[Lunch_Box]

I have a set of 245/45/17 Falken Azenis mounted on some 17x7.5 Volk CE28N with a 43 offset. I have just temporarily mounted one on the back and it is so close to rubbing. As it sits now with the car on jack stands there is about 1mm of clearance, I can slide a buisness car through the upper control arm and the tire. I will be rolling the fenders but what size spacers would you recomend?

Check the front, too.

If there's already some space, then 3mm spacers should be enough.

Keep in mind that the only reason this working is that the rims are so narrow. If you decide to put those tires on proper-width wheels, you're going to need an (effective) offset that's below +40mm.

I've only seen mass produced spacers in 5mm, 10mm, and larger incriments. A 5mm spacer effectivly giving you a 38 offset should place you right in the range that will tuck and still should clear on the inside. Depending on your drop you may still need to roll the fender. A 10mm will change the offset to a 33 and will contact the fender.

The axles are out on the front so I am not able check the front at this time. I wont be getting new rims any time soon, the Volks were expensive enough and the only reason I went with a 245/45 was that I got them for free. Also this is a drag car so the extra little bit sticking out on the sides isn't as much as a concern.

Would you need longer studs if you went with a 5mm spacer?

That all depends on the wheel design and the lugnuts. Easiest way to tell without breaking out any measuring devices is to count the number of turns it takes to tighten a stock wheel compared to the Volks. I know on the stocks for a '99 uses a flat seat and part of the lugnut recesses into the hole. My Koseis use a conical or tapered seat.

5mm is still quite a bit of thread loss, so I would go with longer studs.

http://supercar-engineering.com/ sells very nice 3mm spacers for our cars. The reason I suggested these is that 3mm is small enough to allow the wheel's center to get a good grip on the hub flange and allows you to use stock lugs on most wheels. So, if 3mm is enough, this is the way to go.

In my defense I wouldn't call those mass produced =p

Added to the fav list.

So you think 3mm would be enough since the wheels aren't rubbing right now?
