Iv driven both and felt that the c4s brakes were more reponsive and seemed stronger yet lighter. Pretty sure its because of the dualmbrake boosters. Has anybody actually tried to changed the boosters of the c2s using the ones for the c4s? Might be a good upgrade.

 

Any chance the C4S had better tires?

 

I thought the 997 C2S & C4S had the same brakes and booster?

 

Nope on both comments. The 2s and 4s basically has same except for the booster.

 

subscribed.

never did understand why porsche did not put the tandem brake booster on all 997 models..

 

Not everyone knows that there is a difference. Not sure if it's that big a deal on the street, but maybe it makes a difference on the track????? I never understood why there was a difference between the C2S and C4S braking systems. It would be interesting to know, if anyone can shed some light.

 

Do all the 4 models (TT, Targa, C4) have the additional booster?

 

As is the method of porsche giving each car is own character. The 4 is easier to drive than the 2. The difference in the brakes make the car just a little bit easier to drive on a daily basis. Seriously think the 4 is more the daily driver than the 2. I dont think that the extra weight of the 4 was the reason for the tandem booster but really the feel of the whole package. Which bring me back to my concern anybody try to swap the 4 booster on the 2? That could be a worthwhile mod. The feel difference is noticeable
