Yes you did. I caught that after I sent that to a few people. I guess that's what I get for making that up in the middle of the night.
As far as I know, it's still accurate. It was in XRC a couple of years ago so I guess some companies could have made changes since then.

This is a chart that I have been trying to keep current. It includes Manufacturers listings, other people's testing and the tests XRC did a while ago using the Integy spring dyno. The HPI springs that are in light blue are the suspect ones and probably shouldn't be used. I have aa spring dyno but haven't had time to update.

BTW, the XRC weights are for individual left and right springs tested.

All the independent tests I have seen seem to prove one of two things. Either:
A - Springs are incredibly inconsistent straight from the manufacturer.
B - The spring dynos used to measure these springs are very inconsistent.
Since all the springs I have seen are wound virtually identically I am fairly sure the production method is sound.
For that reason I have personally stopped worrying about measured rates and just use springs as the manufacturers rate them, and only use one brand of spring on the car.

Actually manufacturing tolerances for springs is very hard to achieve. Do your own testing, but for the most part there will be inconsistencies.

Anyone know where I can get an updated spring comparison chart. Associated vs xray? Thanks

Does anyone have the SpecR spring rates as lb to add to the comparison?
Thanks.
Thanks.
