Trying to plan out my future suspension setup

On a side note Shaeff and also IJ, why do Progressive springs suck so bad?
and specifically shaeff why did you not like your pro-kit?

 

[IJ.]

Our suspension is rising rate by design (ie: progressive)

It just blows through the soft part of progressive springs so you get a wallow then normal.

 

[BigKO]

hmm so basically when its not in the firm area of the springs its too soft and is pretty crappy?

 

[IJ.]

Think of it as anti sway bars

 

[BigKO]

oh so we are going boating today? lol Thanks off to work now!

 

[Jerm]

Hey I got a question

So you say that the suspension is rising rate by design. How does the mechanism for that work?

Is that intrinsic to double-wishbone suspenion? Or is there a specific ...thing that does that

 

[IJ.]

Length's of the arms to the pivot points.

 

[sk6471]

One thing that no one on here seems to say is, if you have a pre 89 Supra and you want to lower it slightly with slightly stiffer spring, the 89-92 springs were shorter and had a substantially stiffer rate.

 

[BigKO]

Hmm that would be nice, but I already have a 91, so apparently I am looking for even stiffer than that...

My ride is on H&R springs. They are the biggest drop and a stiff linear spring.
I scrape my downpipe on the taller speed bumps...not cool.
I still run the illumina IIs.
TEMS isn't very noticable once you move away from OEM spring rates.
Even though H&Rs are stiff, the supra will not be the honda that bounces, and ride quality is way better than an air bagged pickup.

I'm running Whiteline sway bars, medium setting up front and soft setting rear. They keep the car flat, and is much more predictable handling over stock sway bars if you happen to swing the rear out accidentally.

Oh thanks, how do you like the Illuminas? That kind of a drop definitely has its downsides, I am not looking for a huge drop really, and I think the RSR's are what I have decided on.

 

[IJ.]

Really big drop fucks up the roll centres and the car handles like a pig anyway

 

[GC89]

For Reference what drop do your coilovers provide Ian

 

[IJ.]

From slammed to almost stock ride height GC.

It's cool to see folding mirrors lol.... I like that design better because when people walk by carelessly in parking lot they don't rip it off... Ans yeah that is pretty low

 

[GC89]

Thats definitely low, I assume they aren't adjustable on the fly and the perch setting controls height? What do you normally have them set at for best ride, handling and probably most importantly weight transfer.

 

[thedave925]

I think the illuminas with my drop are not the best combination. I've been salivating over bilsteins as a stiffer shock without going overkill.

I do believe switching to stiffer sways also negates the factory choice for ride height when it comes to roll center. I've never driven a stock supra so i don't know.

 

[kabanimk3supra]

I have a related question..

If I were to get H&Rs, can I add spring spacers to raise it so it doesn't scrape all the time?

what kind of effect would they have on the handling?
