g60luke Posted September 28, 2009 Share Posted September 28, 2009 Hi, Have notice that since I have had my Zed (only 6 months) that on particularly bad roads where there are cambers/bad textures/dips that on odd occasions the back of the car feels a little fidgety almost as if there is something a little loose on the rear suspension...?! There are NO noises at all so cannot hear the bushes, and on normal roads or even enthusiastic starts there is nothing?! I have noticed it with and without any throttle? Is is possible that the active handling is sensing the car being pulled on bad roads and braking a single rear wheel?! Because that would explain it?! This is REALLY SUBTLE, and just me being a really picky car owner!!! Cheers Luke Quote Link to comment Share on other sites More sharing options...
Beavis Posted September 28, 2009 Share Posted September 28, 2009 Faulty or worn rear shockers have been known to cause this iirc. But if you have Bridgestones on this as been a cause too with their stiff sidewalls. Quote Link to comment Share on other sites More sharing options...
g60luke Posted September 28, 2009 Author Share Posted September 28, 2009 Got Falken FK-452 tyres on the back... Dont know how stiff they are?! Is there a simple way of checking the shock? Quote Link to comment Share on other sites More sharing options...
Ekona Posted September 28, 2009 Share Posted September 28, 2009 What tyres on the front? Quote Link to comment Share on other sites More sharing options...
rtbiscuit Posted September 28, 2009 Share Posted September 28, 2009 falkens are a bit soft side wall wise, might be that Quote Link to comment Share on other sites More sharing options...
g60luke Posted September 28, 2009 Author Share Posted September 28, 2009 Falkens on the back, and Kenda on the front. Dont blame me for the Kendas since the garage agreed to put tyres on there when I bought it! Seem OK though... Does the Z dislike different treads front->rear that badly then?!

Seem OK though... Does the Z dislike different treads front->rear that badly then?! Change your front tyres ASAP. Hell, if you can't afford two new Falkens then match the Kendas (whatever they are, I assume it's Korean for DitchFinder) for the rear as well. Four matched tyres (even crap ones) will be better than mis-matched tyres full stop. Mixing tyres really isn't a good thing to do on any car, regardless of power output or engine configuration or whatever. They're the only thing keeping you in contact with the road, and you'll have vastly differing grip levels fore and aft depending on weather, road surface, speed, camber etc which can end in neither you nor the car knowing which way round it's supposed to be going.

helimeddaz Posted September 28, 2009 Share Posted September 28, 2009 What the ***K is a KENDA ? Is that Japanese for STOMIL, that's what they used to put on Skoda's and Wartburgs. They made them out of wood and old nuclear submarine water seals. Get -em off quick (oo er) or that noise you're hearing wont sound as funny as you disappear into a ditch backwards at high velocity in bad weather.

Trev-the-Rev Posted September 28, 2009 Share Posted September 28, 2009 Maybe an obvious suggestion but check your pressures, they need to be 35 psi. Quote Link to comment Share on other sites More sharing options...
alessandro Posted September 28, 2009 Share Posted September 28, 2009 I have a similar problem but with the front, took the car to Japex and found out that my shock absorbers were gone. Quote Link to comment Share on other sites More sharing options...
rtbiscuit Posted September 28, 2009 Share Posted September 28, 2009 the fact that these guys don't even list them shows how good the kenda's are http://www.tyrereviews.co.uk/Tyre/ Quote Link to comment Share on other sites More sharing options...
Chris`I Posted September 28, 2009 Share Posted September 28, 2009 Could be tyres, could be shocks, could be geometry. I would sort the tyres first, then geometry leaving shocks as the last resort Quote Link to comment Share on other sites More sharing options...
Ekona Posted September 28, 2009 Share Posted September 28, 2009 Maybe an obvious suggestion but check your pressures, they need to be 35 psi. Not necessarily, the exact pressure will depend on tyre brand and in particular how stiff the sidewalls are. For RE040s 35psi is spot on, for something like T1Rs you'd want a couple of psi more in to account for the chocolate sidewalls. Not too sure on the Falkens though having never personally run them.

Got Falkens on mine and run them with 35psi all round, no unintentional twitching so far. Quote Link to comment Share on other sites More sharing options...

Something between 35-37PSI is what I run my Falkens at. Can be a wee bit soft at 35PSI depending on how you like it Quote Link to comment Share on other sites More sharing options...
g60luke Posted September 30, 2009 Author Share Posted September 30, 2009 Checked my pressures and the Falkens on the rear only have 30psi in them...! That will explain it....! Cheers everyone.. Quote Link to comment Share on other sites More sharing options...
Ekona Posted September 30, 2009 Share Posted September 30, 2009 No worries, glad you got it sorted. It's surprising how great an affect on the car a pew psi here or there on the tyres can make. Quote Link to comment Share on other sites More sharing options...
rtbiscuit Posted September 30, 2009 Share Posted September 30, 2009 in my old MR2 roadster i used to be able to tell if i had lost just 1 or 2 PSI as the difference in handling was so noticable. Quote Link to comment Share on other sites More sharing options...

Good that it was something easy. Maybe you should be checking your tyre pressures once a week. Quote Link to comment Share on other sites More sharing options...
