After this season ends, I plan on sending my Koni Sports to Truechoice for a rebuild. I was going to have them custom valved and go stiffer in the rear with spring rate (I use 400F/300R springs) but the lot I now run in my region (13 out of 20 or so autocrosses per season) is worse than the one we were evicted from; thus negating my desire for a stiffer shock valving when softer is now the way to go due to the crappy surface.
My question though surrounds the nitrogen gas charging in the shock. I believe it's there for oil temp. stability, yet a lot of stock class cars have it removed making the shock hydraulic only... And considering the soft spring rates most stock class cars have, wouldn't that overwork the shock oil and cause it to overheat?

So is the removal of the gas even beneficial for STS?

Or should I just have the gas charge retained when I get the rebuild?
