ST165 Spring Rates...

Fri Jan 27, 2017 6:02 pm

I'm building my own coil overs for my 88 AllTrac. I'm using KYB AGX front inserts on all 4 corners. I plan to run lower dampening in the winter and stiffer in the summer. I also want summer springs and Winter springs.. I'll be using some universal sleeves from summit racing. I might use 8 to 10 inch long sleeves for crazy amounts of adjustment.

I live in Anchorage Alaska and our road maintenance budget has been slashed over the years due to the lack of snow for the last few winters. So when we got dumped on the last couple weeks, the roads became rediculous. Many cars stuck on the side of the road in the 4 or 5 foot tall snow berms. You would think that snow being soft and fluffy would be smooth to drive over on the roads...Nope. Damn roads turn into trench warfare...

I want to build a rally style suspension with some actual travel to soak this crap up. Anyone else out there on the forums build a rally Celica? What are the dimensions of your springs? I know the factory rally cars were getting close to 8 inches of travel. But I'm sure that was all custom work. What kind of travel does a stock st165 have?

I went with 350lb front and 300lb rear. All 4 are 12 inches long. These seem to do the trick. Lots of travel, yet still sporty.

Bumping this back to ask how your suspension build went? I’m just about to pull the trigger on redoing my suspension and your post caught me because of the similarity in what I am trying to achieve. How did your conversion for the rear with the KYB’s go? Also; what springs did you end up using, I’m not really sure what my options are in terms of getting a set of coils when I do my strut work.

I did the conversion on my Camry Alltrac.
Converting the rear housings isn't too difficult. Shock wise I've been trying some different things but if someone would be willing to measure the AGXs that'd be appreciated.

I went with Ground Control sleeves and Eibach springs(through Ground Control). I had to modify the upper spring seats provided - but I think they offer a kit for the Celica(they don't for the Camry). I also removed my stock spring perches in order to fit longer springs and give myself all the travel possible. Overall I'm happy with the kit, although I had some difficulty pre-compressing the springs to get the correct ride height (the sleeve spins on the strut). However, if I had found a set of steel sleeves I probably would have done that.
