I plan on running swift spec R's with Koni sports and I'm hoping that coilover sleeves like the ones on summit would work with this application.

No going to work unless you plan on having custom perches built onto the Koni's. Then you'd also have to find a new plan for an upper mount as well. Only other option would be to have the bodies of the koni shock threaded so that the coilover sleeves can be screwed onto the Koni insert. I know some people in the MR2 world that did this for Autocrossing.

I'm 99% sure you will void the warranty through Koni and if you're going to go custom route like that, you're not going to be able to run Swift Spec R's, you'll have to run regular Swift Metric Coilover springs. Spec R's are shaped and built to work in the stock spring perches and upper mounts.

What would your goal be? to have the Koni/Swift R setup and be able to adjust height?

 

Yes my goal was to do the koni/swift combo and have adjustable ride height but id be happy if with that combo I sat about 0.5ish inches lower.

 

I'm not worried about warranty voiding btw.
