I have seen a bunch of pictures recently of comp front springs that have a large number of coils, such as the auction at http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&category=34200&item=2
I've had two types of NISMO comp springs side by side, the number of coils was different, as was the wire diamter. I worked through the math, and the spring rate was essentially the same. The spring
If the wire thickness and diameter is the same on both springs then more coils = softer springs. Stock (early) springs are 6.5 coils and use 1/2 inch wire thickness. The pair on ebay are almost 8 coi
Interesting. Which ones are lighter, and by how much? - RWM /// datsun-roadsters@autox.team.net mailing list /// Archives at http://www.team.net/archive
Just a guess but here goes - spring rate is dependant on OD, wire diameter, and the number of active coils. Two springs with the same OD and length can have the same rate even though one has fewer co
Or save a few cents with a cheaper wire or maybe they already did and compensated with using more wire and then ...nevermind. I think the later ones are softer by looking at the pictures but I wont m
The original comp springs had fewer turns and smaller wire diameter and were made in Japan and sold thru NISMO there and Datsun Comp/Nissan motorsports here. When the US motorsports dept could not ge
