Anyone own ceika coilovers?!

Yes 11" is 280mm right? So with the st165 suspensions, we have to increase the track by 120mm !! (60/70mm on each side) isn't it?

 

Just to add my 2 cents, I've always built my own coil-overs and toyed with different spring rates for different tracks. Here are the front struts I just made final mods on with 7" 550 lb.ft. springs, Koni Sport inserts and cut-down KYB bump stops. I am still going to play with even higher spring rates, but only after some track testing.



The latest set up is the strut on the left along with the brake bracket removed...

Also here are SuperPro urethane bushings from Toyhead Auto Restoration installed in the '95 Celica rear control arms with adjusters rather than cam bolts!

Mafix> yes of course, leaving the fenders intact wasn't an option! But since the clearance with the shocks is already tight past 215 tyres. The extra 6cm with the wider wheels and tyres is all going to go toward the outside. So i'm wondering how the car will behave with such as wider track. Surely stiffer springs will come handy with the increased leverage.

About the 6kg springs, i agree with you. It's just the best spring rate in my opinion for someone who wants a good sporty ride but still have some comfort and reasonable travel. For gravel rally, we go with 4kg 240mm springs and digressive type shocks. Then a lot of the ride quality will come down to the dampers. Not saying that overdamped is good, especially for longevity. But depending on valving type (digressive/progressive) it will make a huge difference. With digressive types I've had customers increasing spring rates over previous Tein coilovers. And they ended up with much better comfort on the street and less body roll/better handling on the track.

racerb> looks really good. Love the clean bench too. Of course it's the cheapest route to go. But base adjustable mount that lets you adjust the height independently from the spring preload is not possible with sleeves unfortunately. If you are serious about handling having the car corner weighted and the preload set on each corner separately is something that will improve the handling considerably. The car will be more neutral and will let you get full control of the geometry settings. But i'm sure they do the job really well! Are you running slicks? Higher spring rates might be good with slicks. I've seen some people getting best result/fastest laps by running high spring rate and no swaybar for track cars. (not on celica though). I wouldn't do it on a street car though, it would give you a sore back to get to the point where you don't need a swaybar.

I miss my st165

 

Going to try it without the front bar and a 18mm Whiteline rear bar, but if the balance isn't quite right, will probebly look for a small front bar!!

 

Cool, let me know how it goes if you test this.
