I scrapped my 5 link because I went to double a arms. Built an upright and arms. Pics are on here somewhere

I have quite stiff springs.... in the ballpark of 1000 lbs front and rear, but the ratio in the front is some 70% instead of the back, where the ratio is very close to 90%.
Basically I use near zero preload on the springs.
This is the reason I sed that QA1 have not enough fluid control to dump such spring during fast wheel travel (bumps or curbs).
If you have seen the inside of a QA1 coilover, you can imagine the reason of that:
the piston diameter is very little and the oil recirculation is demanded to a small tube of less than 1/8" ID.
Of course during quick compressions the bump/valve is fully opening, overwhelming the knob adjusting which is mainly working on the oil recirculation.
For this reason, QA1 will be allways over-dumped in slow movement ( roll control or general control of weght transfer ) and under-dumped in fast movement (road/track bumps or curbs).
Penske are very exepsives (in the range of 1000$ each) but is an other history!!!!!
My next move will be to reduce sway bar stiffness, thanks to the rollcage frame stiffening.

QA1 is juk, the only quality coil over they sell is what used to be the carrera coil overs and even better the advanced carrera coil overs. I'm not even sure if they still carry it in their bling bling line but they did buy out carrera shock co.

Ralphy, What is the reasoning for parallel equal length trailing links?
