Just browsing around Koni's site for whatever reason and found they offer a Koni Sport Suspension Kit, which includes 4 Koni Sports (aka Yellows) and matched springs. Drop is supposed to be 30-35mm (1.2 - 1.4in) all around. The Fox part number is 1130-1700, SN95 is 1130-1701, both list for $678 on their site. I called Summit and was told $635.88 for the Fox kit (I would assume the SN95 kit would cost the same) and it would take a week to 10 days to get. www.shox.com
appears to have the kit for $632.80, and they do free shipping on Koni stuff, so I guess that's the best deal.
Their website doesn't give any details on spring rates, so I emailed them - we'll see what they have to say. As for the generic advertising on their site, it says:

With KONI lowering springs the centre of gravity of the car is lowered. Combined with a firmer suspension this will result in even better steering qualities and reduced body movement. The use of lowering springs requires special damping characteristics: the mere application of stiffer springs together with ordinary shock absorbers often has a negative impact on road-holding and comfort, and may even lead to dangerous situations.
Therefore, KONI's product range offers you complete suspension kits consisting of matching springs and dampers. Of course, the lowering is limited to such an extent that the car will still remain suitable for normal street use.
Nothing unexpected there.
I'm actually interested in this for someone else, as I'm pretty well set on suspension stuff. I met a guy at the last lapping day out here who has a beater Fox GT. It was his first track day, hadn't had the car very long, and he and I talked a bit about improving the car and exchanged emails so we could continue the discussion. I mentioned the Bullitt kit to him (he's not rolling in dough, so he was looking for good, inexpensive improvements). This Koni kit is 1/2 again as much as the Bullitt kit, but the Koni is actually designed for the Fox, so there wouldn't be any fitment issues. (Of course, he could do the Bullitt kit + MM C/C plates to solve the front strut length issue for the same cost as the Koni kit...)
So, Cliffs Notes summary - Has anyone tried the Koni Sport Suspension Kit? How did you like it? Is it worth the money?
