D.D.

I did the search for a loooooooooooong time and could not find exactly what I need to know. I woud like to add the largest spacers I can on the rear of my car just to brin the tires to the edge. The car is stock and not lowered. Factory 5mm do not seem to do enough??? Also, where can I purchase these....Thanks.

You can find spacers at FVD - they include the longer lug bolt needed too. I know 5mm doesn't seem like much - I've used 7mm and they seem to fill out the well. Maybe others have used larger ones.

17mm seems to be the usual for the back of the C4S.

LeonardZ helped me select a set of Ruf spacers and associated lugnuts for my 996TT.

At this point it seems the best setup is 15mm spacers with pressed in studs, and new lug nuts for the rear, and 5mm spacers with stock lug bolts for the front.

You can call Ruf in Dallas and ask to speak with Wayne Corley.

You probably should go with longer lug bolts with spacers. Porsche and FVD both include longer bolts with their 5mm product. I know that Posche uses 17mm spacers with the 67mm offset wheels on the C2 - I'd be worried that 17mm on the 51mm offset wheels on the C4 might be too much. The guys at Wheel Enhancement usually have great suggestions - call or email them.

I have 23mm spacers on my C2 S with 305mm/19" rubber and that is tight! So I'm not sure how that helps you but uhhh I thought that might help??

Oh and with 23mm spacers the car looks sooo mean! But I made the mistake of putting 23mm spacers in the front to, it makes the front end 'hunt' a bit if you hit a bump, crack etc. Nothing serious but I'll probably change them to 14mm or something in the future.

I went with H&R 7mm spacers on the rear of my 2007C4S with the 305/30 x19 tires and it looks perfect to me. Any wider and it would start looking like a rice rocket.

I think this is good advice.
I have 5mm on my C4S with the stock Classic 19" rims and 305 rubber and it looks just right to me. With lobster or classic 19s, a 5-7 mm spacer is probably just right without making the car look blingy - not to mention the fact that the handling dynamics will likely be totally screwed up by just widening the rear track.

I have 18mm in the back and 5mm up front and love the look.

If you have the Carrera Sport wheel on a C4 you should have at lest the 17mm spacer. The rear Sport has an et of 67mm while the other Porsche 19 inch wheels for the C4 have an et of 51mm.
