Suspension by the Numbers - Car Setup How To

I wish our coilover kits put the springs over the rear shocks instead of maintaining the stock, separate position for the springs. I guess it's a clearance issue.
 
It would make calculations easier, and strange things happen with the rear motion ratio and the springs.

Overall, not a big deal.
 
A lot of the images are still in photofuckers here I believe: http://s64.photobucket.com/user/phate1985/library/phate MS6/Suspension?sort=3&page=1

I'm able to grab the images through some magic (ctrl+shift+c, find the real image link, wget it to my desktop... ok, so not really magic). I was planning to go through the posts here from @phate and try to correlate the images I found to the post, and then upload the images here. Not sure if that's effective though. I could maybe grab a list, upload them to the forum, and a moderator could just change the links?

This is one of the more useful posts I've read.

Sorry guys. I've been meaning to do this, but have been going full bore getting the car ready for the season. I should have time to upload everything to the MSO server in the next couple weeks and add the pics back in.

Psssst, been a couple weeks :)
 
Honestly fellas, the references he cited contain most everything he discussed here anyway. Check 'em out.
 
Interesting series with some seriously flawed perceptions. Why would you include the bump stop in the spring rate calculation? If you're driving around on those your coil springs are way too soft. No consideration for front/rear drive? No consideration for the impact of unsprung weight on ARB? The calculations and theories contained in this post do contribute to predicting understeer/oversteer, but not in a vacuum.

Bump stops should only be included if/when you are using them as a main spring - or more so for when you do use them. That will help you understand the behavior for when they are utilized. It's a missed aspect, most people just toss them in without regard for their rate, let alone when they engage. [I actually mentioned this in the first post, if you read it.]

No need for front/rear drive consideration. The roll bias calculations are just that - steady state roll bias. The fact that your drive type is one or the other doesn't influence the roll bias. A different quest is how to effectively put down power - and sometimes that leads to compromises in roll bias in order to obtain better application of power. [Or, for me, a balance of roll stiffness contribution between the main springs and ARB's that didn't compromise roll bias.]

What in particular do you mean about the unsprung weight influence on the ARB? I'm not sure I see what you're getting at.
 
Hey Clint, how's it going? I know I'm late to this, but is it ever a good read. Are you able to run different engine/trans, diff mounts in your car? I'm looking at building mine like this for a street/track car.

Yep - If you want, start a new build thread and give me a mention if you have any questions.
