Just be sure to make the rotational difference between the front and rear less than 3% otherwise you will have issues with your transfer case when picking out tires. I just went through the hassle of putting 997 5 star wheels on my 01 C4 but well worth it as it looks SOOOOO much better. The wheel fills the wheel well so much better.

Wouldn�t do it�

Thanks for your reply. But still it does not helps me, I want to be sure if below sizes and offsets will fit my 996 CS4 Narrow Body, I am looking for experts advice before going for this change, Kindly guide Porsche Wheels RW06 19x8.5/19x11 5X130 Gloss Black Chrome Lip fit 997 996 911 Carrera - Wheel Brand: Aftermarket Product - Size: 19x8.5 Front, 19x11 Rear - Offset: +45mm Front, +40mm Rear - Bolt Pattern (PCD): 5X130 - Hub Bore: 71.6mm - Finish: Gloss Black Stainless Chrome Lip - Fit : Porsche Carrera Wheel and Tire Package : - Tire Size: Front : 235/35/19 Rear : 305/30/19 or 295/30/19 Your valuable advice and guidance will be appreciated.

The rears definitely won�t fit. Google an offset calculator. The stock rear wheel is 10 inches, with an offset of 65mm. You�re talking about coming in 25mm with an inch wider wheel. That�ll definitely rub. btw�chrome lip? Just, no.

Have you already purchased this aftermarket setup?

I have the following sizes and all are all within tolerance (rotational F/R). Front: 8" width rim 57 ET (but I use a 15mm spacer meaning it's really 42 ET because if you don't it will rub the strut). 235/35/19 Rear: 11" width rim 51 ET 295/30/19 My car is 2001 C4 Hope this helps

Thanks can you please recommend best fit / size of wheels front and rear for my 2000 model 996 Carrera S4 Narrow Body. I am not an car expert and the workshop here in Bahrain doing a project on my car does not have a clear clue what sizes rims / wheels I should get ? Pls help. Thanks and Regards AH

The S4 isn't any different other then you don't have to worry about rotational sizes. In other words you can put whatever you like as long as they clear the strut & wheel well. With that said my car is a narrow body car and I like the flush"ness" of my wheels (offsets they have) What are you looking for? Wider? Flush with wheel well?

I believe a narrow bodied car is a C4, not a C4S, which is a wide body car. Two different wheel setups, mostly at the rear of the car. That said, the rolling diameter of the wheel/tire combo remains critical, keeping it at less than a 3% difference between front and rear diameters. Also, a 19" set up will give you a somewhat harsher ride.

Porsche did NOT release an S model narrow body from the factory nor was there a C4S in MY2000. You more than likely have a C4. Porsche also never designed the Mk1 cars to support 19x11" wheels. The fender's edges are not rolled and will cut into the tires. The widest is 10" for the rears on the narrow body cars and even then Porsche required 265mm wide tires to compensate for the lack of fender edge roll which was changed in the Mk2 996. People have made 19x11" rear wheels work on the Mk2. Heck, I had them on my 2002 Mk2 996 but they scrubbed. Awful ride qualities too. Removed them and went back to a factory 18" Turbo Twist.

My 01 C4 runs 19" with 11" in the rear and 8" in the front without issue. No cutting or rubbing. I am running a 15mm spacer in the front to keep it from rubbing the strut tower but other then that there is no issues....at least that I've had.

Sure, but not with 40mm offset wheels. This thread has gone some places so that may not be in play at this point, but that�s the key factor.

Following this thread. Tire fitment is wizardry and witchcraft to me.

True.....but the front will work with a 40mm but the rear will stick out a lot!

What is a cs4 anyway? Maybe you better show us a photo. Probably a C4.

OP, just post your VIN so we can know what the hell is going on here.
