Not sure where to put this but HELP:)

Just fitted coilovers on the front of my 206 and is lowered right down with helpers out very low :/ on 15 inch wheels drive shafts are not hitting anything because i have looked but the gear box feels really rough now like vibrating but only somethings really doing my head in. could it be its to low :/?

cheers

I take it the suggestion return to stock is not what you're after?

try less lower?

really your question is answering itself.
just rephrase.

"I've seriously altered the suspension and steering geometry of my car, far and away outside of what it was ever designed for, what should I do?"

the simple answer, if put inside the range that it was designed for, even if that doesn't mean go back strictly to stock, then try going not so low.

Yea going to have to when I get home.

I Will tell you the story what happen drove to my grandads on normal shocks and dampers but my bearing on clutch was going. Then fitted coilovers and left my grandads but with out testing them I did a bit of a wheel spin so im not sure if its because its so low or if the bearing has really knackered now :/

I think best thing to do is higher the car test it if then still dont run nice new clutch then if its still like it new gear box? is that what you would do?

cheers

When you alter the suspension you alter the angle that the drive shafts are at.

Think of a triangle... school geometry and all of that.

If you lower the suspension very drastically you physically shorted the distance between the output shaft and the hub. and your drive shafts end up being too long.
The drive shafts being solid chunks of metal aren't going to be shorter just because there are compressive forces on them, so you stress everything either side of them, in this case your hub components, (drop links, roll bars, bushings and bearings).
Your steering components are also out, track rods etc.

and at the other end of the drive shaft you stress the parts that are now making noise, likely to be your differentials with would now being pushed all kinds of awkward directions.


With what you're saying now, I'd return completely to stock, and see if the noise is still there. if the noise goes away, I'd then lower until the noise comes back, then back off.

(if the noise is still there)
You know that the clutch needs changing anyway. so try that, if that makes the noise go away again I'd lower in increments until I saw problems, then back off a few increments.

but after returning to stock, and replacing the clutch, if the noise is still there, then you probably broken something inside the gearbox, my bet is the diff.
replace that, look at the bill a few times and consider whether you really want a lowered car any more.

Thanks for that I will give it ago to night and up date on here.
