not to be a prick or know it all but just saying my opinion and what has worked for me. i picked up 2 tenths at the track on street tires with this susp setup. For the front I swapped on a set of old completely blown junkyard front struts with 4 drilled holes per strut to make sure the strut had no resistance going up or down. i removed my Tokico BLUE's and left my stock springs. By allowing the front of the car to lift up so easily it causes the weight of the supra to load on the back tires thus helping with traction if u can control the weight transfer properly. Now with my soft fron susp my rear end would squat to much (REAR Tokico Blue's and stock springs). When the IRS squats to much ur lose camber thus u launch on the inside edge of ur tire which i really noticed when i looked at my "walking burnout marks." I would only leave a dark 2 to 3inch patch. To fix this i measure on a alingment rack that the IRS can travel 1 3/4 inch with out losing camber. So i modded a set of 4runner bump stops so rear end can only travel about 2 inches then it bottoms out on the stops. Now the whole this in motion work better than i hoped. The front end lifts up at launch causing the rear to squat. Except rather than the it squat 2 far and lose camber it stop on the bump stops. This allows the entire weight transfer to "slam" the tires in the ground but with 0 loss in camber. I know can cut 1.8 and 1.9 60's ft at the track on NORMAL street tires. This is just the setup i found to work best launching MY car on the track and on the street. this is just my opinion... feal free to compliment or criticize
the car rides fine on the street except the front end is a lil sloppy.
THIS IS A DRAG LAUNCH SUSPENSION not road race ect...

I understand ur point totally with my setup i cannot corner on the onramps or dart thru traffic. But this system is the only way i have found to get good 60 ft time DRAG RACING wich is driving straight ZERO conering involved. Anyone who does drag racing know that 60ft time is was makes or breaks a good ET, and if u ever go to a street car shootout just about every car there will have super soft if not blown fron shock and they race on skinny's. I now realize that i dont think there is one person on this forum who has a real interest in drag racing a MK2 as i love to do. Which i understand becuase everyone else drives there cars daily on the street. The setup is not for a street car but for a drag race car. I know the setup is not meant for the street or for drifting ect. I apologize for posting this since i guess no one drag races their MK2 on a weekly basis and this setup is not meant for a street car.

BTW 14.02 on streets for under $500

Heres my setup
85 p type
fully loaded leather sunroof from the factory
MODS Cut open air box Stock toyota filter
3inc custom side pipe exhaust still has factory cat Cost $50 in raw pipe
Zex 75 shot bought used for $250
6 NGK R 22retc plugs $20
Used Apexi AFC $100
Tire Michelin Pilots 225/60R14 at 20psi with good burnout
As i said this is my set up. i dont have fire breathing 7mgte just a 150k mile 5m on spray. If i was trapping in the 12's i would stiffen the front end up some of course i dont have a death wish. I am willing to make a set of these custom stops and u guys can try them out and see what u think. The biggest problem with the IRS is when it squats to much we lose camber thus we lose tire contact patch. this is how i found to beat that problem. All i wanna know iis what setups u guys run to help ur launch at the track. I understand if u have a HO 7mgte that ur susp is going to be setup alot different.
i can get 1.8's and 1.9's 60'ft on michelin's not slicks not even drag radials. I plan on getting a set of BFG drags soon.
