Jellybean Posted February 7, 2017 Share Posted February 7, 2017 (edited) Was talking to to Alex in Nitron , might be worth making a sticky Supra Models NTR R1 SYSTEM 2-Way combined damping adjustment. http://www.nitron.co.uk/pwpcontrol.php?pwpID=17759 NTR R3 SYSTEM 3-Way independent damping adjustment. Independent adjustment of rebound and fast and slow compression damping. http://www.nitron.co.uk/pwpcontrol.php?pwpID=17760 Spring Rates We can use any spring rate you like assuming it’s a increment of 25lbs. Track focussed car would be 700lbs front 400lbs rear. For a fast road setup we would suggest 625lbs front and 375lbs rear. CW recommended 600 lbs ins fronts and 320 lbs ins rears http://www.mkivsupra.net/vbb/showthread.php?318772-nitron-shocks&highlight=spring+rates Can they supply Progressive Springs? We don’t use progressive springs (Variable rate aka Non-Linear ) I’m afraid, we use Straight (Linear ) Springs Good read: http://automotivethinker.com/suspension/linear-vs-progressive-rate-springs/ Service intervals Service intervals are very much case dependant, for example an endurance race car should be serviced every year to maintain optimal performance whereas a weekend road car can get away with years without a service. We suggest servicing every 12-18,000 miles for a road car, obviously if your car is used on the track mainly this mileage is greatly reduced due to the much higher operating temperatures. I always tell customers to regularly check the adjusters are still turning freely and the clicks are still as positive as the day you received them and to keep the piston rod lubricated and free of debris and then to use your best judgment of when they will need to be serviced, most people service every 3-5 years. Dust boots Sadly we don’t offer dust boots for our shocks, you may be able to find spring socks that would effectively do the same thing. I found these Spring Socks: http://www.motamec.com/motamec-spring-cover-coilover-protector-shock-bag-red-13-330mm-long-pair.html http://www.motamec.com/motamec-spring-cover-coilover-protector-shock-bag-black-16-406mm-long-pair.html Compliancy If you want to focus on track performance then obviously you will have to sacrifice compliancy for the road, we try to keep this to a minimum however as performance is our main goal you will notice a difference. We also use spherical bearings rather than rubber mounts so you will encounter more road noise. Spring rates for a track focussed car would be 700lbs front 400lbs rear. Let me know if you require anymore information.
