I can't find info on their site for the Yaris. How do they compare to the BC Racing DR series installed on my sedan? Are they more daily-driver than track use?

The B14 kit is what is being used by all makes in the SCCA B Spec class - which allows non adjustable (rebound/compression) coilovers. I think quality wise they are better. However, the springs that come with them, like most coilovers, are street springs. For the track you would swap the springs for stiffer rates. The BS guys are running around 400lbs springs with the B14 kit.

Gotcha. I had considered converting my 09 HB from daily driver to B-spec when it gets retired but I'm not ready to do that just yet. That would also involve removing the 2ZR and custom C50 setup, so that's a pretty far gap to close. I think I'll pass for now.

Imo it would be way more fun to keep the big motor and run in STL.

do you know what the spring rates by chance?

I don't know, they don't provide the rate. They are progressive, certainly what I would consider a street spring.

That's where the old ArmstrongRacing "Project 2ZR Vios" is headed. ;) Gonna take some ballast to get back up to 2400 lbs though. It's currently around 1800 without the cage or driver, and I've lost almost 80 lbs over the last year. I figure I'll do a couple seasons with the 2ZR and if it looks like it has even a chance of hitting nationals I may pony up for a 2ZZ swap and get some real numbers under the hood.

Updated price. Time to get these out of my garage.

Hmm, I think I may be interested. I'm running the original B-Spec kit, which was probably more cosmetic than performance.
