I'm really glad you mentioned this because I have a question on that. I looked up the H&R spacers and there is a kit for the 996 with 7mm front and 14mm rear spacers, plus new, longer lug bolts all-around. I actually ordered it and then cancelled because it looked like 14mm was going to be too wide for the rear once the car was lowered. So you used the 7mm on front and back? The question then is if the hub part of the rear still retains enough "lip" to hang/center the wheel on? With the 14mm, the spacer integrates a new hub lip as part of the spacer, but I assume the 7mm without the lip works fine on the back as-is?Yes, spacers are a must IMO and will match perfectly with the H&R setup. I have 7mm + H&R springs, and gives it a stance similar to the 996.1 GT3.
