ECU....cause it looks like everyone nad their mother (at least on 6speed) is going HRE P40s...That would make it too common IMO
(similarly, on the 996TT almost everyone here had a Techart kit at some point LOL)

 

H&R - 7mm front / 15mm rear

 

I second this. you will get more performance and better looks out of this for sure!

 

ECU will feed ur speed hunger better than wheels would and that's why u got TT first off.

 

the car looks good stock, go for the ECU. plus, you can beat GT2s with this mod

 

I third this..adding more power won't make you a better driver. Admittedly adding coilovers won't either but it'll make your car handle a bit better. I just picked up my car after getting them installed yesterday and it's bar none, the BEST mod I've ever done to my TT.

 

you know what I would choose

if you need some help let me know - as our previous cust i'll take care of ya

 

ECU because you'll have more fun. the wheels will make your car look better but what's more important? looks or a good time?

 

Sell the RR and get everything for the TT. Stop messing around.

 

Wheels were the last thing I did..
