JustinOlson Posted May 6, 2009 Share Posted May 6, 2009 I have a set of 36mm Bilstein inserts that I would like to have re-valved for my race 280z. For the linear only 30mm piston bilstein inserts (P30-0032-HO) it is recommended to have them valved 300/100 for linear valving. That is Bilstein's notation for 3000N/1000N at 0.52m/s. Since I have stepped up to the larger diameter Bilstein insert, I have the option of going to digressive valving. How does a linear valving of 300/100 correlate to a digressive valving. My track width tire to tire will be ~71" I have YZ fenders front and rear. My spring rates are 375 front 350 rear. My weight with driver should be around 2400-2500lbs.

JustinOlson Posted May 6, 2009 Author Share Posted May 6, 2009 I found the valving manuals from bilstein, but they don't really touch on this: http://www.bilstein.com/dl.php Quote Link to comment Share on other sites More sharing options...
JMortensen Posted May 6, 2009 Share Posted May 6, 2009 http://farnorthracing.com/autocross_secrets16.html This page has suggestions for where the knee in the valving should be and how stiff the valving should be. Is it right? I dunno. How about you try it and let us know??? Quote Link to comment Share on other sites More sharing options...
TheNick Posted May 8, 2009 Share Posted May 8, 2009 Talk to Marcus Meredith at Margrave Motorsports http://www.margravemotorsports.com He revalves Bilsteins on the side of his real job - I've ridden in his ESP Mustang that had 1200lb+ springs and you couldn't even feel the bumps on the course.

johnc Posted May 8, 2009 Share Posted May 8, 2009 Although not specific to a Bilstein shock, the Penske manual will get your mind moving in the right direction. http://www.penskeshocks.com/files/Adjustable_Manual.pdf Quote Link to comment Share on other sites More sharing options...
