It's my opinion that with the right roll stiffness and sufficient rear droop travel that you can reduce rear inside wheel lift to an inconsequential level on an STU Evo.
Hey Steve,
Can you please PM me a price quote with current delivery times for your coilovers. I sent an inquiry on your site but have not recieved a reply. Please include whether or not they come with upper camber plates and pillowball mounts.

Thanks,
John

Steve,
I agree 100%. Both the STi and the Evo really benefit from increased droop travel in the rear. I feel that's why a lot of coilovers (including your's) uses helper springs to utilize full droop and allow the main spring to keep tension.

I know not all STU guys use coilovers with helper springs, so in others' opinions, can one be competitive with the typical non-helper spring JDM type coilovers that rely solely on roll stiffness?

Branden has won STU twice in a row at Nats on Tein Flexs.

Just got done spending the day adjusting my new Zzyzx coilovers. If these things perform half as good as they look, I'm going to be very happy. I'd say go for it!

Chris, I'm stoked for you. You won't be dissapointed.



Just a note too guys. The white car is 2-0 against Mr. Burkhart and I drove mom's black car to a two tenths win against him as well today. He is beatable believe it or not.

I was there, I witnessed it. Those constant transistions weren't very friendly to my stock suspension, ofcourse that is no excuse for my lame performance ... Jake you have improved tremendously as a driver.

Why the focus on droop travel? does it matter where you wheel is at if there is no load on it?

It does when only 3 wheels are on the ground in order to maximize grip.

Dave Mac, Not sure if you have seen this. Here are some pix of the test and tune at Fedex courtesy of TeamWTF. Those guys are the best! Enjoy...

I'm in any time! Sounds like we may have to hit CBRD to go at it on GT also. Derek is fast on the slots.

Derek and I were talking today, looks like we are going to try and get the car out of the barn this week, WOOOO HOOOOOO! There are some parts to get on it and probably some more tuning by Chad to get it ready.

changing the wheel's postion with respect to a particular load isn't going to put any more load on the tire. AKA, won't produce any more grip.

The rear droop travel issue has more to do with getting power down early than with added traction. The extra travel will just make sure the tire is on the ground early enough (with some load) so that sufficient power can be put down without wheelspin.

Thanks for posting those pictures Dannykao. I can't wait to get the RS setup. Wheels are here this week and suspension should follow shortly.

Do you think an upgraded rear diff would be a better solution?

edit: obviously not a better solution for STU. But maybe in general?
