Springs for MCS 2 way on 997.1/3
I have a set of MCS remote reservoir shocks 2WR system with Generation 2 canisters to put on my 997.1 GT3
I took them off a crashed race car that I parted out. Sent them to MCS for rebuild and now need to install them.
The spring rates were 800# front and 1000# rear. The fronts had a thin helper spring and the rears had a much thicker helper spring. Springs are Hyperco 6" length x 2.25" ID
So, my question is what to install now.
I considered putting the 800# in the rear and buying a pair of 600# for the front. Car is semi-daily / occasional track day / occasional mountain run.
would 600/800 be too stiff? Or maybe go softer?
Also, as far as helper springs go, Should I use them? Shouldn't they all be the same? What size?
Any suggestions appreciated.

Do you know what spring rates/weight the shocks are valved for? usually the "0" setting is setup for the base spring rates - just make sure you have sufficient adjustment if you change. My car has Ohlin TTX on it. I run 650/800 with very low rate helpers on my 997RS and it's good, its not 'soft' but its not overly jarring either and one you are at road speeds its good and supple, even more so at "higher than road speeds" and also, good for track.
Sounds like you may have tenders? Usually a helper is about 10lbs or so, just keeps the main spring located. A tender can be higher rate and help with spring rates at higher speed compression around town (sort of a dual rate).

I have mcs single adj. around 560/840. Very comfy on the road, much smoother than stock. Work well on track. Weren’t faster than stock really but just much smoother over bumps

Thanks for the comments.
Seems like I was pretty close with my 600/800 estimate. I'll put some tenders, same front and rear.
I'm not sure what they are valved for. They came off a 2011 GTS track car with 800/1000 springs. I sent them in to MCS and they rebuilt them but I never asked their valving (didn't occur to me) and they never mentioned anything about it.

600/800 seems fine for your use.
I've come to really, really like using low rate tenders (100-170 lbs or so) for both better track and street manners. Gives just enough rate for keeping inside wheels planted and/or from spinning in high droop situations on street or track, and also softens the initial "blow "for bumps in street driving. There's a reason the big boys like Bilstein and Ohlins both come standard with low rate tenders in their high-end double adjustable Clubsport and TTX setups, because that's exactly what it helps with. The TTX I just bought for my 7.2RS come standard with 30 N/mm (about 170lbs), same for Bilstein clubsport kits. Outside of adding cost, there is literally zero downside to running them.
I run them on every car I own.
