steering rack

just thinking outloud - is it possible to modify a steering rack so it doesnt turn as far? like instead of being 2.7turns lock to lock, it's 2.4? obviously that increases the turning circle, but is it possible? and if so, how?

after market bumpstop?

doesn't the crossbred kit have something to stop the steering from turning to far when the new knuckles are installed?

yeah something like that, but not just a forced stop like a bumpstop, something where you adjust the steering rack internally or something

Are you talking about stopping the wheels from turning so sharp or having them turn just as sharp as they do now but with less turns of the steering wheel to do so?

If its the latter you'd have to find a steering rack that has the appropriate ratio, or have bits made up to fit your steering rack that creates the ratio you're after.

I think the L's steering ratio is something near 3. something larger than 5...

Yep, 3.7 per '89 fsm on the L series, thought my rx was a little better than that though

talking about keeping the ratio the same (ie the internal gearing), but not allowing the wheels to turn as far - so basically stopping them from turning so sharp.

the best way i can describe it is say the stock rack can turn the wheel to a 45 degree angle. i want to stop the movement of the rack so that it stops at say a 35 degree angle

so when you go to big big tyres, they dont scrub on the inside on full lock

well the cross bred kit comes with nylon bushes that go on the end of the rack to do just this, although all later model subarus have a much worse turning circle so you could always bodgy one of them to fit!
