Let's talk IRS set up
Let's talk IRS set up
so I have tried many combos and some worked some were way off. I have been waiting for a Set of hks drag coil overs to come up for sale but no luck. I have been 90% happy with the way the stock touring rear springs and struts work. The 2 issues I have is, they sit too high and the are a tad soft. I feel like I bottom out just a tad. Maybe 25lbs harder would be perfect.
I have used koni yellows with stiffer springs, stockers in rear with stiff coil overs in front and my jic's that are way to stiff.
My stock set up was pretty consistent to 1.3's - low 1.4's on a good track... Good enough fo me..
Just can't take the jacked up redneck look.
So I called jic about converting these stiff coil overs to a drag coil over. We discussed what all would be needed and I decided I would just try myself. Had them deflated to 80psi in the cylinders. Ordered some 8 inch 200lb springs. Installed and it just went to the ground. I had to almost preload the entire spring to get the car to a usable height. So I ordered some 225 springs and added 2 inches (10 inch) I had to preload these (compress the spring) about 2 inches and it sits perfect. I was going to go Friday night to test but ended up running out of time.
My thought are the preloaded springs are going to want to raise the rear too fast or make it bouncy?
I think I may be trying something that just won't work.
Now on to the front.. I have just been using my stiff jic's on the hardest setting. I was reading some last night on a drag chassis set up and it said the front would rise faster on softer springs and less dampening setting? I don't see how but sure I am wrong. I would think you would want to preload the **** out of the front so it would rise fast and have a stiff spring-damping to keep the front up and rear plante?
The rear I would think a double adjustable strut with correct spring weight to allow the rear to squat quick without bottoming out then have the dampening on the rising side set so it rises very slow the entire pass?
Educate me please!

Btw.. I got the shifting dead on with my combo. More power may come later but I have a goal to run 9's on current 67mm turbo, via Mazda driveline, axles, etc...
This, but front and rear. The spring keeps the car off the ground. The damper controls the motion. If you still have your Konis, I would suggest talking to them about converting then to double adjustable and custom valving them for your purpose. They sell a coil over sleeve for the 42mm body shocks made for the FD so you can go to a custom spring.

Sold them. I have spoken to koni before on this. After I just decided to pick up some hks drag shocks but it's been hard to find them.
Would be nice if a guy could adapt some Afcos, or something similar. Would probably be cost effective to do the fab work to use a true drag shock versus reworking a Koni or similar.
