It sounds about like what they would say about my car if it had a PPI. If it's just surface rust on the rotors, you don't need to replace them. That's normal if the car has been sitting. Especially outside.

On the tires, just be sure to get the F/R diameters right. 19's can be a little tricky. There are only a couple of combinations that will work properly and not cause problems with the front diff or weird PSM behavior in hard driving.

Otherwise enjoy it.

Thanks, ssst.

What are the right combination tire sizes for a 19" wheel? i did a search and I didnt get a satisfactory answer. Personally, I do not like that size. Perhaps, I should swap them for 18" before I replace the front tires.

My first 996TT was tracked with vigor, and was my DD. Car was well maintained with frequent oil, trans, diff, and brake fluid changes. The car had 10's of thousands of type 1 and 2 (I don't remember the exact number). The guy who bought it did exactly the same as me, drove it hard, but maintained it well. Last I heard, after several years, it is still going strong with no engine issues. YMMV

re wheel sizes...

the ride quality, stance and handling on a properly setup 18 ride is dramatic as compared to 19's which i found to be just awful. but not many seem to feel as strongly about the 19 vs 18 issue as i do. i merely rely on the factory gt2 wheel sizes and ride heights as arrived at for reasons other than aesthetic and that 18's are optimal for the car. i think you'd be wise to at least compare driving both setups if you dont just go for wider 18's e.g. gt2.

Keep in mind Porsche tunes their suspension based on certain fixed parameters. The 996tt came with 18's and the suspension is designed for 18's. One of the factors other then handling was the car is used on city streets so in addition they wanted a little more comfort for the driver. 19's have a propensity to ride much harder due to the sidewall height being less than the 18's. Longer drives are more tolerable. With that said I would think using 18's and adjusting the suspension height etc. would yield a very good compromise.

kalyan

Yeah, I agree. I prefer 18s too. Perhaps, I will put it for sale and see what I get and then get 18s. Maybe someone here wants to exchange!

mdurbahn

Hmm I was wanting 19's and in colorado too, maybe we can work something out.

kalyan

Oh cool! Look forward to that. I should warn you tho that my front tires need replacement (rears are pretty new) and one of the wheel has some curb damage (both according to PPI).

Those numbers look fine. I think people make too much of the over revs. The only way I know of to erase the ECU data is with a new ECU. I installed a brand new ECU this past spring and all over revs and engine time went to 0.

SSST

Honestly I'm not sure. You can do a search and find some posts on it. I was thinking about 19's but after researching it, I decided against it and have expunged that data from my online memory. Maybe some of the guys that run 19's will chime in.

I'm a believer that these cars are very well engineered within certain parameters. When you start to get outside of these parameters, you are taking some risk that requires experience in automotive engineering and Porches specifically to understand what you are getting into. These aren't Honda civics where almost anything you do will be an improvement.

You can easily go backwards on these cars if you aren't careful.

toward that point. i just read a quote in a "mod" thread and i'm paraphrasing but a guy said ( and at times he'd certainly be right..) that:

"the part you remove is often better than the one you just put on". referring to aftermarket parts of course.

Agree the factory parts are usually very good quality and most people never drive their cars hard enough or have the ability to see any gains from performance upgrades= at least on a car with 996tt capabilities.

"02996ttx50

i'm staggered you could say that!? not being argumentative, but the full potential of the entire car isn't even nearly approached, until one modifies it! i truly mean that. i suspect you have pristine low mileage example and perhaps less time in mean and durrty ol modded tt's

they are night vs day from stock ones.

rmc1148

I'm not saying you cant improve on stock just that most people never use the potential of the car stock much less improved = this car can out perform 90 some percent of owners as is. Just an opinion.

"02996ttx50

i'm with ya on that. if i had to pick a number though i'd guess mine was 25% faster/better whatever ballpark over a stock car, and that 25% is where all the fun lives
