I would go with Tokico. I've heard no complaints about them. Bilsteins to me just seem too mainstream. They're a good shock but thats what I have on my 4 wheel drive.
I had the Illuminas and although I had no complaints, they aren't as good as the Koni Yellow DA's I have with my Griggs C/O setup. The Illuminas are adj, but one way. the DA's are "double adj", which means you can fine tune the compression and rebound. The Bilstein in my opinion are excellent replacement from stock, but they are not adjustable. The Koni's (DA) I think are the most expensive out of the bunch but as they say you get what you pay for.
KYB which i'm sure is Kayaba, are budget on motorcyles, i run Ohlins on my bike sooner than anything else.
I also have heard good thing about the Strange adjustables- and at $70/shock and $119/strut-- they are darn good prices. Within the next couple weeks I should have a set of Strange shocks on-
i'd go strange over anything else, they're built strong, they work great, they're 10 way adjustable and priced good, can it get any better than that
yup i love my strange's they are great for the street and the track. I have yet to crank them all the way yet because i haven't autocrossed the car with them on. But at five on the street they are amazing for the price.
yea i know they are cheap but a few of my friends have been running them from three years now and no problem. They haven't blown or anything and they all drive the wheels off of their cars.
