metric chassis ride height?

[stillfast]

Trying to help a friend set up his mod. We don't know who built it, but it is a metric clip, metric spindles and lowers. I is a 2 bar rear suspension with a pull bar. It will run with UMP. Any help on ride heights for the metric clip? Springs? Bite? Thanks

Lf 6.5" @ bottom of frame rail before dog leg.
With 700# 9.5" tall
Rf 7-7.25" same place w/600 spring 9.5 tall
K772/K727 ball joints
Rear springs 175/225 RR on top LR infront
Dont remember rear hts. 130# bite
Lr bar 2" shorter then RR bar
Short Pull bar with quickcar buiscuits 1/8" preload change every 10 nights run @ 18*
No wrap up shock
Short bar on slick/j bar on heavy/tackey
Lr bar 20ish* rr bar 10-15*
shocks Lf 75 rf 74. Lr 95-3 (gas) Rr 94
Cross 52 left 52.5 rear 57-58 on alky 56-57on gas

Now this is what worked for me on a sandy track check with some people at ur local track to see what they ran. May have to drop bar angle/bite/cross for a track with good clay!

Thank you. That is enough info to get us going.

Kojak, are those springs rates for metric lowers, or nova lowers?

Looks pretty soft for metric lowers....

Yes metric lowers! I know this always starts argument but i have always had success with those spring rates. My current car 4/4 is all metric and run 700/650 with a tie down shock on the Rf! Everyone says u cant run that soft of a spring on metric mods but i know of alot of cars that do and even run lighter then that. Ive been doing it since 03 and dont plan on changing it! Alot of people say they bottom out and i have no idea why, im guessing they are running stock metric ball joints and/or have their ride heights to low. Kinda sounds like they may have a Moment Center issue.

This goes against most rates I've read about, but I'm gonna try a 750rf 850 lf! Does seem like no matter what rf spring rate we have shock travel stays the same!
