Due to the cost of and simplicity 4 identical sized wheels are run on all 4 corners of the st185. The rear fender has a little more flare than the fronts, so a 25mm spacer is more common which causes the rear track to be wider than the front. Many 15mm spacers and smaller require extended lug nuts to be fitted or there is not enough thread for the wheels to be safely installed. The simplest solution is a 20mm DTM spacer that already has studs.

The rear track of the gtfours is shorter than the front which has caused many of us to add rear spacers to add to the looks of the car.įrom the owners manual the tracks are listed:Ī 15mm spacer would be needed on both rear hubs for the front and rear tracks to be equal. These are good tools for calculating offset of a wheel. It will help you determine the clearance between the wheel and the suspension and if the wheel will stick out too far from the fender. Offset is a very important factor in choosing a wheel size. (Various sized OZ wheels may be found on gtfour models in other countries.)

Camber also affects things here, even only a few degrees of neg. If you crave deep dish like me, you know that the lower the offset, the deeper the lip you can obtain. Keeping in mind the AWD, you most likely want to have all 4 wheels identical in at least width. If you're like me, for the circuit you prefer to stretch the tire and use as wide of wheels as possible. A 9 inch wide wheel with a near 30mm offset, as stated above will also do nicely and should fill the fender well.

This means a 10 inch wide wheel should fit with an ideal offset of +10 or +12. The max we've seen on the rear so far is 130mm on the inside and 120mm on the outside. This means a 9 inch wide wheel on the front is very possible with something near a 30mm offset. The max we've seen so far on the front is 142.5 mm on the inside and 82.5mm on the outside. This means the stock wheels extend 47.25mm out past the hub and 120.25mm inside the fender from the hub.ġ7x10 +5 (sticks out slightly but has 12.5mm of clearance on the inside) Rather than scatter the information in various threads, this thread's purpose is to educate all ST185 owners as to what size wheels are possible on their vehicles.
