Re: 90/10 Front Drag Strut
i use em for street and strip.. they are basically the budget drag strut.. if you can find them, use worn out stock struts.. and when i say worn out, i mean worn out to the point that it can even hold its own shaft up..

Re: 90/10 Front Drag Strut
My Iroc is not a daily driver but, i drive it a lot in good weather. I don't think i feel safe driving around on worn out struts all the time. LOL
Re: 90/10 Front Drag Strut
As for 90/10's they're fine for a non daily driven street car that's looking for a little more off the line. If you drive on them a lot they have a tendency to lock-up. If you're running in the sub 9 sec range they tend to keep the front end up to long and allow extra air under the car, thus causing less stability at higher speeds.

Re: 90/10 Front Drag Strut
I use Koni SPA1 struts.
If it's track only 90/10 will work. If it's street/strip, I'd recommend 70/30.

Re: 90/10 Front Drag Strut
Different worlds by all means, but I've already been in the low 1.2 60ft range with the 10.5 car and it's got Monroe gas-matics. New, but cheapies. I've only got 2" of down travel anyway.
I went 1.66 on 17's in the vert with a 5-speed on the regular KYB's and stll have the stock WS6 sway bar on it.

Re: 90/10 Front Drag Strut
yeah, i mean one day the car is going to be just a track car but for now i still like to get my 60 feet under 1.9's. I will just have to see if i like the 90/10 struts on the street/strip or not. What about not running a front sway bar does that help at all for off the line?

Re: 90/10 Front Drag Strut
Get rid of the front sway bar. Keep or install a rear sway bar.
Re: 90/10 Front Drag Strut
decent rear tires, lower control arms and relocation brackets(if neccessary) should easily net you 1.8-1.9's w/o hurting its handling/driveability in any way.
I went 1.87 on a basically stock suspension(eibach lowering springs and relocates) with nothing more than decent tires and a heavy stereo system in the trunk. At craptastic speedworld I consitently went 1.87-1.90 my first year of college. - A set of drag radials, the stereo out, control arms and the relocates I went into the high 1.7 range.

Re: 90/10 Front Drag Strut
well what i got now is rear boxed control arms, relocates, stock sway bars , eibach lowering springs, all poly bushing, weld in subframe connectors, 9bolt BW with 3.27 gear, street tires BFGoodrich and a 3k stall. Best 60" so far was a 1.91 when 13.57 at 102. but im planning to lose the front sway bar, get 90/10 struts, and a spohn torque arm. See what i get then!

Re: 90/10 Front Drag Strut
don't bother without getting real tires if you want to see what the car is truly capable of.
