I've had mine for 2 years now...just sitting in my living room, waiting to get installed. These were pretty easy to order from Japan. Interesting enough, the fronts can be ordered separate from the rear so I ordered Ti-2000 down for the front & Ti-2000 half-down for the rear.

 

Why would you do that?? It's not going to sit or handle as intended.

 

I think it sitting not the way it's intended is the point in this case.
Handling is another scenario, but considering most IS's are used as daily's, I don't foresee it an issue.

 

FWIW here's the spring rates for the RWD Ti2000 springs

 

Yup, if they are at all similar to regular RSRs in drop and he wants a level stance, he's gone the right route (imo).

 

I somewhat wish I had done this. I have the RSR Downs on my car and the rear has pretty much no gap and the front does which somewhat bugs me. I plan on getting coilovers next though so I don't see the point in buying half downs for the rear.
