[Jackthewack]

i appreciate everyones advice and i will do some reading into the affects of springs and shocks as advised. if there are any more sights or builds that have good info i would love to read them. just started looking into vorshlag really cool stuff

OP,

IMO you need to think about why coilovers vs stock system but different parts. Understand the limitations of the stock style like no ride height control without changing springs and no control over corner balance.

A good coil over will:
-not use a divorced spring design because that's not a coil-over
-address potential stress to the REAR shock mount area by ensuring that the shock body is engineered for a length consistent with ride height run. In other words if RH is lowered shock body needs to be shorter. partial fixes for not doing that homework are offset shock mounts. assuming stupidity of owner making larger shock mount with additional attachment points. A good rear shock design will not bottom out in extreme function. It will provide the travel needed to allow suspension to do its job. bottoming out is never good!
-rear coilovers need some kind of offset lower mount to give extra clearance to CV boots that grow at typical 130+mph on track
-allow you to corner balance the chassis
-allow you to customize ride height
-allow you to source a number of manufacturer's generic spring diameters, lengths, and rates for near unlimited choice
-allow additional camber at the spindle
-allow the use of any camber plate
-allow easy adjustment if adjustable (rebound/compression)
-have adjusters that actually do something
-provide real shock dyno graph
-are rebuildable and revalveable by known pro shock rebuilders in the industry with easy access to replacement parts
-must provide consistent performance over the entire race distance and not fall off with heat generated.

I'm on vorschlag rates 600/750 with MCS shocks and I'm race only. I have them installed but sidelined with cv19 no scca races

Does anyone have the wheel rate conversion value for rear coil-overs. For the stock rear location I'm using (0.492^2)

I'm kind of interested in the ratio of front wheel rate to rear wheel rate that most people like. On my e46 I ran 480 lb/in front and 240 lb/in rear wheel rates and loved it. The car was underpowered (350hp/3350 lbs), though, much like my ecoboost.

Rear wheel rate at half the front is about where I'm at and this has performed the best for me so far. 550lb front springs, Steeda DR rear ~1200. I'm autox focused though.
