rear-end

[brad19]

Ive read the suspension guide as I have a question
but ill have to ask you guys as it doesnt quite answer it for me...

Ive had my saxo lowered for about 15 months now
Around janruary last year i had the back notched up to roughly a 60mm drop to match the front, and fit my 17's under
The handling has always been excellent
About 3 months ago i got new tyres on the front, replacing my 2 toyo proxes with 2 champiros or something (Big mistake!)
The front end started to lose grip when acelerating trough tight turns where the proxes were excellent
But my question regards the rear suspension, sometime after the new tyres I started to notice it alot
The back end has developed a bad skip over bumps, making me very weary driving it :-(
The suspension guide suggests this will happen with a 60mil drop, but this didnt used to happen
Does anyone have any idea what might have caused this???
My suspension set up is spax 60mil on the front and adj. spax shocks on the rear (Does the dampning rate want changing??)

1) you're lowered 60mm
2) you have 17" wheels
Those 2 are your biggest problems, other than that the shocks might be worn or on their way out.

No it hasn't.

Its skipping because its on the bump stops. The torsion bar is fully compressed and can't move any further, hence when you hit a bump the suspension hits the stoppers loosing grip, it then springs back and the cycle repeats. This is why your back end skips.

DOn't lower it 60mm and run 17s is the best sollution

mine does something similar mate 80mm on 15s

handling is poop but looks good :-)

[brad19]

:-(
it did used to be fine, promise
Ill have someone have a check if they're going out
cheers

[brad19]

just thought id post back. They were going. Only just ordered some now, but its cool. Will have the handling sorted again for the dry summer roads :-D
cheers guys

If they are adjustables and there is room for adjustment on the rears then softern the rear up abit.

The items could have worn badly (unproball but) worth having them checked.

not being picky here dave, but it doesnt matter how low your car is the torsion bars are always under the same compression.

[KamRacing]

riding the bumpstops is the easiest way to ruin your handling as the rubber does not compress too well, the rear will tend to go skippy. I think what David was meaning was that the suspension has no movement. I used to cut down the bumpstops by half on my lowered 205 to make sure that had enough movement, but its better to just not go too low.

I think the suspension gets more floppy the lower you go at the back. The angle of the dampers change I think. This is probably why I've currently got my issue after just lowering it more... I need to adjust the dampers (if they will go stiffer) so it's not like a boat in water.

[KamRacing]

when upgrading the rear its not the dampers you really should be upgrading as a solution, The torsion bars are the eqivalent of the front springs and these are what really will aid your rear end.

[Toad]

Agreed! ...Have you seen the price of those upgraded ones? Flippin 'eck! :panic:
