Ok my GF has decided to purchase the Racing Hart C-2 (3 Piece).

We are planning to order wheels in these sizes:

Front 18*7.5 +50mm
Rear 18*8.5 +55mm

We are planning to order tires in these sizes:

Front 215/40
Rear 245/35

She is also planning on lowering the car by approximately 1-1.5 inches. My concern and question is with the offset. Can anyone recommend a proper offset that will prevent rubbing? BTW since the RH 3 pieces are custom made we can order the wheels in any configuration. Any other comments or recommendations would be greatly appreciated.

Thanks.

 

The offsets you have listed will work fine with the tires you are using. But I would watch how low you go. The rear might rub if you use the wrong tire.
