Swift Track Springs installed GT2RS
Had the Swift Track springs installed on my GT2, slightly firmer ride but good, feels more precise on turn in on the street. I will report back after my first track day. I've used Swift springs before on other cars and have had great luck...

You should track the car stock first. Then make whatever modifications you think are needed, then track the car again and see if there are any improvements or if it actually made the car worse.

Good point and I do get what your saying. I have a good friend who tracks a lot, extremely fast and has had a lot of time behind a wheel of a 2RS. His impressions were the car was too "soft". We both have very similar driving styles so I decided to just try these.. BBI uses them on their set ups also.. This is not going to be my track only car anyway, my ACR is..

Well, it looks the business at the very least. Did Porsche go with a softer spring rate on the 2RS?

I don't believe so. I think they're even stiffer than the 3RS. I can't find an exact number but one article states the springs rates are 30% higher than the .2 3RS, which are 100nm front and 160nm rear.

Interestingly enough my 3RS and my friend's 2RS both went FASTER running the cars with the sport mode off and swaybars in full soft setting. This was at our home track in Cresson, TX on the 3.1 mile configuration.
COTA is pretty smooth and high speed but I would be curious to see. I'd run your car on both sport mode and non-sport mode to see the difference. COTA surface has improved but stiffer springs don't always translate into faster times. You increase turn-in but can reduce mechanical grip on a bumpy track.
Good luck.

Make note that when Randy Pobst drove the 3RS and the 2RS at Road Atlanta for his record laps, Porsche had both the front and rear bars set in the medium setting along with running the laps with the sport suspension setting turned on.

Makes sense the cars were faster at Cresson with the softer settings since that track is very bumpy. At COTA with the smoother surface I would bet the sport mode and stiffer bar settings would be faster.

Side bar- do you happen to know what kind of setup angles the cars were running when Randy drove the cars? I have been curious to know if they set up with bar/aero changes only or if they adjusted the angles of the cars as well.

Good points except I would not blindly assume that swapping to a stiffer spring package would result in a faster car on any track. If it were me I would have tested a baseline with the car un-modified before making a judgement call.

What I do know on this is that Porsche adjusted the cars to the most aggressive factory specs. Camber was maxed within the factory recommended settings, ride height was lowered to minimum factory recommended settings, aero was maximum on the front and rear, but I do not know about the toe settings used on the cars. Randy did run with ESC+TC turned off along with sport suspension turned on. Hot tire pressures on the MPSC2R tire were 35 PSI
- Thank you sir.
