I can't wait to see how you like it!
Version 8 has been fun taking 10+ years of chassis and refining it into the current revision. Lots of "reading between the lines" of what customers say they want VS actually want. Less "peak performance" and more ride quality.
IMO coil overs is a 'buzzword' that people want because they think they are supposed to! My '56 Nomad has front coilovers on it (QA1) which I do not like. I see NOTHING that they do for me... and as soon as I find a decent set of factory front springs, they will get swapped out.
Springs control the car, shocks control the springs. You have to tune your chassis like you tune the engine. This is why I start with the double adjustable shocks at a minimum so you can have this room you need to tune after its all said and done. The problem as you might have noticed is that adjustment will let you screw up just as fast as fix the problem. The right tool for the job. I would say you should talk to a Circle Track shop and get then to adjust your shocks for you.
Honestly it's crazy the number of shocks I have to stiffen up because guys have them dead soft thinking it will help the ride out.
SHOCKS CONTROL THE SPRINGS
read that twice.
You need to run the shocks up to deal with the springs.
That being said. Everything effects everything else. Coil overs are not a bandaid for other problems in the stock geometry.
C4 stuff is obsolete now ,step up to c5 and later they are even making after market spindles for the c6 set up
Yeah, no.
While there are some advantages to the C5+, Newer is not always better.
Especially when taken at a performance per dollar cost analysis in these old cars. The C5/6/7 is just too wide. By the time you narrow it, replace the rack and pinion, replace the front and rear swaybars, narrow the CV shafts, AND get the shocks you need to make it all work you're easily at 2x the price of a C4 sway. And you can't get your rear tires out from under the car. That's the real trick everyone figures out the hard way.
The C4 and C5+ share a lot of the same geometric advantages you need to make a car perform like a modern car.
lots of caster, front mount racks, sway bars, aggressive camber curves, anti dive for disk brakes just to name a few easy to recognize items.
And the C4 package 'just right' for our beloved TriFives when it comes to floor board modifications as well.
When I get to the C2/3 Conversion frame I want to do I'll have a C5+ option but the C4 is still the best bang for the buck.
