can anyone tell me what wheel sizes i should use on the 3rd gen rx7 im planning to put 18x9.5 all round but i have come across sizes such as 19 on the front and 20 on the back why is that????????? Would that affect the drive in a good way to have two different sizes or is it for poxy show offs.....(no offence) I just want it to be right.

also im looking for Racing hart CP-035R im looking for them everywhere


Thanks

 

these are the wheels im looking for:

 

Running a larger wheel decreases the amount of sidewall you have (to help keep the overall diameter the same or similar to stock). This will cause increased road noise as well as more road harshness transfer to the car. IMO 18's are about as big as you want to go on a 3rd Gen RX7 unless you are making a show car.

Having different sizes front and back will not do anything but look a little strange. You'll have more sidewall in the front than in the back.

 

The Racing Harts are discontinued IIRC. What is your application?
