how do people lower their cars 50-60mm when my driveshafts are rubbing with just 35mm

[shiyan]

standard distance from wheel center to wheel arch was 350mm, was lowered to 315mm on KW V2... had a lot of buzzing while on track under hard cornering, turned out the driveshafts were rubbing against the body, made driveshaft shaped dents in the body :dead:

It's been raised to 320mm now, which is 30mm lower than standard, won't find out until the next trip if that's enough...

Are the bumpstops in the KW V2 not located correctly or something? :S

just measured... current distance from ground to top of arch is actually around 600mm all round... if that helps

seems to be about the same as the Trophy's standard ride height according to yozza's page

600mm on every corner? Surly that's not correct. A proper corner weighed (setup) car will never be the same at every corner.

Sounds about right, just measured mine and its 580mm on 3 and the n/s/r is 575mm

Unfortunately I didn't measure them myself before I got the V2 fitted

ohwell the,

my car is fine bar an odd knocking noise, but thats getting looked at tmrw and i have been told its to do with top mounts..

iv never heard of driveshafts being a problem.. seems odd to me mate..

Doubt its a driveshaft, I went this low and only rubbing was tyres slightly...

Huh? Where can they rub? Pics?

Re: how do people lower their cars 50-60mm when my driveshafts are rubbing with just

ph1 is lower to the ground than a ph2 for a start (smaller wheels) so referencing a trophy is pointless. Also the front wings are different....

Can't see why driveshafts would be a problem, there's been some EXTREME lowering without them being an issue

If rubbing they'll probably cause major problems very soon. Bad angle.

I'll take some pictures when I get the wheels balanced today

Re: how do people lower their cars 50-60mm when my driveshafts are rubbing with just

2 shots showing the problem, it is possible that it happened when the car was about 10mm lower than it is now, at 45mm of lowering

2 shots of the car to show its current height:

also, outside edge of what was one of the front tires, now switched to the back:

inside edge:

should I switch the tires between left and right already?

jeez that is odd, never ever heard/read of that happening!? lol?

Stiffer springs and get your tracking looked at

Re: how do people lower their cars 50-60mm when my driveshafts are rubbing with just

Stiffer springs to replace the springs of the KW V2? First I'd have to find springs of the right length, then I'd have to find stiffer springs for the rear to keep the same balance

this is just too odd! never heard of that problem also!

The front's been raised another 10~15mm, and yet I'm still having the same issue under extreme cornering.

I must admit that I am going rather quickly nowadays, have kept up with the Ring Taxi on the 2 latest trips, both times from Carrousel to the end of the lap. First time it caught up with me after some yellow flags, the 2nd time I was going slowly behind a friend, but decided to give chase after the Taxi went past, managed to keep up till the end of the laps on both occasions.

I'm sure the Clio would get murdered on the open sections in the first half of the lap though.

People have suggested the engine mounts as possible culprits, but they've been replaced less than 2 months ago, had them checked today at Renault, and they say that the mounts all seem ok

sounds a bit stupid, but has one of the lower mounts, or gearbox mounts gone? Is a bit strange, but that's renaults for you I guess

I've had the engine mount, dogbone, and geabox mount (under the battery) changed, with standard Renault items. I think there's a 4th somewhere but that seems to be a minor one and not listed on sites such as K-tec

The suspension bushings are Powerflex items, fitted half a year ago

Re: how do people lower their cars 50-60mm when my driveshafts are rubbing with just

something's definately not right. wishbones sitting too high?

 

[DannyR]

Re: how do people lower their cars 50-60mm when my driveshafts are rubbing with just

This is very weird! It almost seems as if the wishbone is coming up to high. Where is it hitting as it looks like its hitting the wishbone from that angle and where the marks are?

 

[shiyan]

Re: how do people lower their cars 50-60mm when my driveshafts are rubbing with just

I'm confused as to the wishbones comment

The driveshafts were hitting the car frame, notice the dark line around the driveshafts and the dents in the car body right above the dark lines.

The photos were taken from the front of the arches when the wheels were removed, with the car lifted up on a bridge, so the suspension was at full extension.

Re: how do people lower their cars 50-60mm when my driveshafts are rubbing with just

Sorry, I didn't see the dents up the top! It seems as if your engine is sitting to high, causing the wishbones to then be higher. Only thing I can think of!

Lol, oh, wasn't looking at the pics properly obviously. Dampers haven't gone have they?

Re: how do people lower their cars 50-60mm when my driveshafts are rubbing with just

i will be checking this thread regularly as it is a strange problem unseen before :S

Rideheight looks fine to me, i'm absolutely baffled !


***edit***

removed my gearbox-mount comments ; cannot be the problem !

Your springs/shocks are no good i think !

 

[franx]

Re: how do people lower their cars 50-60mm when my driveshafts are rubbing with just

... + get in touch with the KW dealer who sold you these ; something is'nt right with your suspension. Only worthwhile option left to check is your suspension

the KW V2 is half a year old

handling is fine, so I don't think the dampers are gone

I'll try

Re: how do people lower their cars 50-60mm when my driveshafts are rubbing with just

It must be something suspension related surely. If everything else is fixed in as it should, there can't be anything else :S
