Any suggestions on what after market spring kit I should replaced my OEM with? Thank you.

Larry Cable

just springs? - and what are you trying to achieve/solve for?

Thinking about maybe track or auto cross the car a few times a year .

I'd recommend then you stick with the OEM suspension (and get it aligned by an experienced shop 1st) , until you have a better understanding of its current OOTB capabilities on track before you start to modify it ... perhaps add a DSC suspension controller which is less intrusive than a spring change and will alter the car's handling noticeably (on and off track).

the car was developed on the racetrack (Nordschleife) and is perfectly capable OOTB - unmotivated and/or ill-considered changes are unlikely to improve the ride or the experience (on or off track).

my $0.02 YMMV

Personally for a few times a year I wouldn't change anything. JMHO

I don't think a GT3 needs suspension modifications for a vast majority of people. The car is way more capable than you are the way it sits.

Is it high mileage, like over 50-60K?

Larry Cable

I agree, I would certainly recommend an alignment though!

^^^^ I thought with stiffer spring the car will not roll as much and handling would improve. So what alignment is consider aggressive ? And what shop you guys recommend here in the north bay ca?

N. Bay not sure (but not S-CarGo) Tony Collichio at TC Designs in Campbell or BRR in Sunnyvale/Saratoga...

if you are going mixed road/track you will want to avoid a very aggressive alignment unless you want to replace your tires very often...

I get the impression (perhaps wrongly - if so, apologies) that you are new to the 991.2 GT3 as well as track driving, in which case I would leave the suspension alone (excepting the alignment and perhaps a DSC) and get some seat time in ...

I'm fairly new to the GT3 world and I had my Porsche dealer maximize the camber without using shims and got -1.9' all the way around. This seems to be a good road/track combo for me so far. If you are on a smooth track use the sport suspension, if it's a rougher surface then leave it on the softer setting.

this 100%

Larry, do you have your own experience with the DSC controller on the .2 GT3? I have had it (the V3) on 981S. Was unimpressed at first only to fully understand its magic once I took it out. My 718 spyder got it with toe links before my first ride in the car. Now with the GT3 I've read some people say, that the added value is less pronounced, that the .2 already has a great suspension etc. If what OP is after is body roll reduction, DSC may well be the answer as body roll reduction is what I have noticed the most on the 981S (or more likely its return with the return of OEM PASM controller).

Just my perception, but both OEM PASM controller and much more so the DSC controller appear to be dynamic in nature to me - meaning that firm setting doesn't necessarily bring firmer ride / less body roll immediately, but only once you really start pushing the car around. So with this I second the advice already given to OP to first push the car hard repeatedly before making any mods to it.

Main advantage of the DSC is better ride comfort on a 991.2 gt3.

Handling wise, far better drivers have said little difference in lap times and some said it made it a bit spooky on or over the limit.

As I rarely track my car, the added comfort is a major benefit. DSC is easy to swap in & out, so a bit of a no brainer, particularly if the roads in your area are poor.

Cheers,

Ive had DSCs in my 997.2 and 991.2 GT3s as well as my 718 Spyder... I agree the DSC is less noticeable on the 991 as the 718 but it does improve roll in corners, brake dive and acceleration "hunker" ... but I dont think it really
adds secs to lap times...

the ride though is improved, and its tunable if you take the time to learn about the app and the effect of changing them, which is not really any different than a manual 2/3/y way shock ...

I think a good alignment (more to check that the car is correctly aligned) along with a DSC are good investments in suspension "modifications" ... anything more than that and then you need expert advice from someone who
has significant experience in suspension tuning for the platform ...
