So I have been doing a bunch of road racing and I have decided its time to do some upgrades. I have a 997.1TT and do about 2 track weekends a month or so and daily drive it the rest of the time. I plan to do the following upgrades at the same time:

1. Either Caragraphic Loud or GMG Exhaust (not sure which one yet. Plan to upgrade turbos in the future so that is part of my decision)
2. Blistein Damptronic with PASM
3. GMG Front and Rear Sway Bars
4. Tarrett Drop Links
5. Softronic ECU Flash

Wanted to get thoughts and/or input from you guys. Plus if anyone knows of great deals for sourcing this stuff that would help as well! Thanks!

Just bought the cargrphic race. Can't wait to hear it. That sounds like a perfect 1st set of mods at once.

 

What about some weight saving ? Like sport bucket seats , a lightweight battery ,lightweightwheels, a carbon hood , and then maybe carbon fiber bumper

 

Sounds like a nice combo. Will really bring the turbo to life. Doing all together or one at a time? Maybe some clutch work too, so it won't start slipping after those upgrades?

 

Another option would be to do some "mods" on yourself Maybe hire a legit, pro coach/racer to improve your skills, or go to a Rally school for car control. I know modding the car is fun but if you're tracking the car twice a month spending the cash on your skills will make you faster than adding hardware to the car. just a thought.

 

Wish I could track the car twice a month... so true, new skills and nothing better than seat time!!!

 

So I decided to go with the GMG Exhaust system and it looks great! My guys are doing the install now and I will post pics and sound clips when the install is done tomorrow. Also, I went a bit overboard with the suspension and did a full (modified) Stage 4 suspension upgrade along with my Bilstein Coilovers. Replaced absolutely everything that is a suspension component and got everything fully adjustable. I went with Tarett for all of the other suspension parts.

With that said, I wanted to get an opinion from you guys on camber settings,

I went with a slightly modified Stage 4 setup, (slightly modified as my 997.1TT is also a daily driver), and I wanted to get your thoughts on Alignment and Camber.

I have seen several posts mentioned doing -1.2 Front and -1.8 Rear, which are the max numbers that the stock components will allow you to do. I do have the fully adjustable control arm and am debating what to do for Camber. I have also seen -1.2 Front and -3 Rear, however I was also told by someone that they would recommend -2 Front and -2.25 Rear, even on the street. So I wanted to get your thoughts and opinion. Thanks!

@RNS I did everything all at once. Install should be complete tomorrow evening.
@E55AMG, Actually I think thats a great idea! Im going to check with my local PCA chapter and see what schools/instructors they recommend.

Sayajin, camber is a tough one. There are much better experts on the forum than myself, I only know my own experience, but will tell the quick story:

When I put on the TPC Stage 3+ suspension kit (an EXPERT installed did it so the car was in good hands), my kit came with camber plates that allowed more negative camber up front. We did the initial install and with the camber plates on it put in a lot of neg (can't remember off hand how much but it was a lot more than stock)...probably around the numbers you are mentioning in your post. [if i get time i'll try to dig up the number but likely wont get to it before you car is done]

With the large neg camber up front the car was dancing all over the place. It was "hunting" for a crack in the road to follow. This would have been perfect for the track but I do mostly street driving. At high speeds it felt unstable and that you would absolutely want both hands on the wheel to keep it in check when the pavement became uneven and the car tried to pull you into any lower pavement, off the road.

I then found out the camber plates as part of the TPC kit actually had 2 install options: standard, which gives aggressive neg camber for the track, but also an option to "flip them upside down, rotate the left/right plates on the car" and you get more of a stock turbo setting for camber up front.

So I had the adjustment made and I'm back to very little neg camber in front. Car is much more stable in a straight line, more fun for me to drive on the roads available to me.

Now if I had a LOT of twisty roads at my disposal and constantly in S curves one after another then the original setting would have been a lot of fun.

My personal conclusion, only from my limited experience:
The more neg camber (especially up front) the more the car "hunts" for a crack in the road and pull you off the road....aka the less stable it is going fast in a straight line...and the more tire wear you get on the inside edge. BUT the more grip and even tire wear you get when spending a lot of time flinging the car around the corners.
