Well, you have two problems. Modding is the obvious one. Second, you're getting into DE's. Very slippery slope. If you really think you're going to get serious about track driving be careful about spending money on the turbo to make it a track rat. It's tough to do and at the end of the day you still have a very heavy, very expensive street car.
I did this to my previous cars and while it made the car more fun to drive on the track, I had to live with the harshness for the remaining 97% of the time I drove it on the street. I think what drove me over the top was the lightweight flywheel. Going from a dual mass flywheel improved engine response, it sounded like a cement mixer for everyday driving. Drove me nuts.
I've learned my lesson so now I keep my street ride close to stock, and save the crazy mods for the track ride.
. Ordered GMG springs and sways to lower and help with track. I'll at least keep all my stock parts in case I want to switch back.
The amount you'll end up spending on the TT will go a long way towards a track-oriented car.
This is a never ending cycle. I started with a perfectly good, nicely modified Turbo and in two months have totally redone the engine, suspension, wheels/tires, rear seat delete and am dreaming about the next steps.
Don't listen to anyone, man. Just pass the pipe!

More importantly, a dedicated track car will be much safer on the track and you won't have to worry about wrecking your expensive turbo.
As I said in my other post i went thru this and ended up with a track car (you can see what I got by searching for it here. I think the thread is "new toy" or something like that). If i had to do it all over again i'd probably still do the suspension upgrades as I think the car really needs it. I could have done without the power upgrades. There's just no where you can drive the car on the street near it's stock power, nevermind 700 hp or so.
Everyone is different but I would say if you plan on doing 10 or more track days a year get a car.
