I haven't heard any real-world feedback on the TODA racing coilovers. the specs look nice. The 8k/f 5k/r seem a little odd, but they might be valved differently. For that price however, you might want to look at some OHLINS or the like. Those are very proven.

I take it you are looking for dual-height adjustable coilovers right?

 

You are going to find the coilover selection for the Impreza that have independant rebound & dampening is very limited. Very hard to find unless you spend the big bucks. However, dual-height adjustment is easier to find: JIC, Higher-end TEIN, Cusco Zero2r, couple others.

Gary Sheehan has used these on his Touring car WRX with good results.

OHLINS for impreza:

I use JIC FLTA2's on my 04 wrx. The street ride kinda sux but they are great on the track for the price ($1699 retail). They needed alot of little tweaking to be good though, Out-of-the-box they are less than steller.

Also keep in mind the 05 STi has different suspension than the 04 STi. (thicker hub carriers, couple other little things) so 04 designed struts will not fit, and vice versa.

Btw, welcome over to the impreza side, I've seen you over at corner-carvers.

 

The only zeal coilver I see that is for the 02-04 impreza platform AND has independent rebound & Compression are the Super Function R's that retail for $4,441,50. yikes.

I would REALLY look more into the DMS and OHLINS.

Are you hell-bent on independant rebound & dampening control? I take it you know what you are doing with that level of control.

in the 2k price range, JIC's can be the ultimate set-up for the price but they do have to be tweaked a bit from what you get out-of-the-box. (custom spring rates, etc). The JIC's have features that are normally on much more pricey coilover systems.

A good person to talk to that is an expert on setting up JIC systems for real racing, street and open track days is John Mueller at Road Race Engineering in Southern California. He really knows his stuff. One warning, he does have quiet a "personality" that some might be turned-off by but he IS knowledgable if you can get past that, some can't. It might be worth a call to John to just find out more about them. (562) 777-1522

The KW V3's look really nice and they do have a great track record overseas. One thing to keep in mind is while they are independently rebound and compression adjustable they are not dual-height adjustable. If that matters to you. I don't think V8VENOM is looking to lower his car lower than what is normal so it really might not be an issue.

 

Dual-height adjustable means there are two ways you can lower/extend the strut. One the usual way at the bottom spring perch (like ground-controls) and the 2nd way at the strut body bottom where it connects to the hub. The advantage of having dual-height adjustable coilovers is that you can change the length of the shock at the bottom adjustment point and it will not change things like preload on the spring, travel, etc. You basically set the preload and travel with the top perch and adjust the length of the shock (lowering or raising the car) with the bottom adjustment point.

You can cornerweight any coilover system, dual-height adjustable or single-height adjustable. Any system that you can independtly change the height of each corner of the car, you can corner-weight.

Egan, didn't you used to have JIC's? Those are dual-height adjustable. Notice the red ring at the bottom of the spring and the additional red ring at the shock bracket area:

 

Heh, I know what you mean, I had a GC setup on one of my Talon TSi's and that sound is not very confidence inspiring.

Rob, how did your Griggs setup on your mustang compare to the coilover solutions you are looking at for your STi?
