Actually we all have coilovers, but what I am referring to is "Tein Flex" or "Ground Control" type adjustable coilovers (re:Phlash69's setup). You should consider cornerweighting your car. It provides better balance during transitions.

Anyway, I am doing that for the miata and and found that OPM Autosports is THE place in town to do it. http://www.opmautosports.com. They also do performance alignments and other stuff too.

I'm curious, what do they use for adding/balancing weight and what do they charge for this service?

Glyphon

i'm not positive, but it think balancing is achieved by adjusting the height at each corner. no adding of weights. hence the need for adjustable coilovers.

Phlash

well, that makes too much damn sense......I know for a fact that my ride height is dead on at each corner but I bet I'm off on weight just because the settings at each corner were all different......

I'd be curious....i just need the scales....

There is the rub... apparently the four scales needed are over 1 grand each to be that precise for that much weight.

The process goes like this:
1 - Unhook sway bars (you'll want adjustable sway bar end links too, check with Racing Beat, they may have some)
2 - Ballast the drivers seat with the approximate weight of the driver
3 - Check weights
4 - remove wheels
5 - Adjust coilovers per calculations
6 - put wheels back on
7 - repeat steps 3 - 6 until 50/50 diagonal balance is gained per calculations
8 - hook up front and rear sway bars (adjusting end links so there is no "preload" on the bar (the bar isn't twisted when you attach it, it's just resting)
9 - remove ballast
10 - pay the man
11 - Leave in the most balanced car you will ever ride in.


It also wouldn't hurt to check alignment in there after the corner weighting is done.

I'm not sure on price, my coilovers arrive next week... but it's a one time thing. Once it's done, it's done, unless you change the weight of your car significantly enough to throw it out of a good 50/50 diagonal balance or if you ever mess with your coilover heights.

Oh, and these guys are highly regarded by the autocrossers and racers like Gran Turismo East is.
