I'm in the process of doing a few upgrades and would love to hear what everyone has to say...

1. I'm thinking of running GT2 spec wheels with 245/35/19 & 325/30/19. I think the awd-system will be safe with these specs and I'm hoping the sidewall will match up all around. (prefer a meaty setup)
2. Can't figure out with what tune to go with. I see many are running COBB off the shelf tunes or custom Cobb tunes... (I'd love to run a catless setup)
3. As for springs, I'm stuck between eibach or h&r springs. Looking for a spring that will lower the car a little, but not overly stiff as I'm planning on picking up a DSC controller down the road... I've heard people complain about their h&r springs being too stiff.
4. I'm also going with a 2.5sachs clutch.. anything else I should consider while the transmission is down?

Thanks in advance! Super curious to hear everyone's thoughts and experiences!

 

Welcome to the club and congratulations on the purchase!

1- I run cup 2's in 245 and 325, no issues but I'm running wider than stock rims, never tried them on the OEM rims.
2- Cobb is a really good platform with alot of tuners out there and it has solid features, You can go with AIM performance or Sam from by design, they both tune Cobb. Sam usually has good package deals and you can get everything from him and his customer service is quick. There may be other tuners out there but these are the common ones.
3. I'm running Eibach springs and was worried they would be stiff, I did not notice any difference in ride quality.
4. No idea

I strongly recommend you consider the following mods as well:
A- Free flowing exhaust system.
B- Do88 intake pipes
C- Aquamist System
D- Intercoolers

Good luck.

Congrats! I love my 997tt more and more each time I drive it, actually on my second one now!


Those tire sizes are fine, I run 245/325 on my oem 997.1tt wheels with no issues


For springs I actually have an extra set of H&R springs laying around I would let go for cheap, they belong on a car being used as opposed to sitting around in my garage! I wouldn't worry about ride being harsh, especially if you go with those thicker/taller tires


congrats again and keep us posted!

 

I'm running H&R springs on my 997.1 and I love it. The ride quality stills awesome even with PASM on.

I would suggest a set of sway bars. For me, the stock 997 suspension has too much body roll and understeer.

On the remap matter, COBB + Sam from by desing is my choice any day.

 

Congratulations!

 

Welcome to the club
Your going to love it even more after modding ..my opinion would be as follows...
Kline exhaust ...custom Cobb..ams coolers... do88 pipes...
gmg springs
It is true that gmg rides a little harder but I couldn’t tell the difference between them and the and other brands plus your tpc controller will really level this car out...you want to be able to control your 600 ponies with the best handling springs on the market...I’ve had my gmg springs for 4 yrs no problems no sag with a good ride...

 

sachs 2.5 is great.
