WhyKe10

$45 fitted and balanced were for 155/80/12, I didnt know they made 165/75/12's (and I would expect they would be more expencive because they are less common). I just got some 175/70/13 (because of the ke55 brake upgrade) for $55 each. The shop was Tyre Zone Cleveland 123 Russell St CLEVELAND 4163 Ph 07 3488 2690 Cheers grant

Deffinatly check the tyres out. I only started this thread because I though i tested the car with good/balanced wheels. I couldnt believe how big the flat spot was (probably from the car sitting still for 2+yrs), I'm surprised the vibration was only at 60km/hr and not the whole time :y: If the tyres are old and worn, treat yourself to a new pair, $45 each fitted and balanced!

It turns out in the mayhem of wheel changing, the car somehow ended up with the same wheels on the front which were the problem, A massive flat spot will do that. Relieved I don't have to fix anything, but i still can't figure out how those wheels didnt get rotated.... strange. thanks guys Grant

Like the title says, it only happens at around 60km/hr then dissappears. It is probably the worst vibration I have ever seen. I put a different set of wheels off my ke10 on and that had no effect (they wheels off the ke10 may not be balanced) I guess i really should spend some money and get the wheels balanced first. But say its not the wheels, where do I start? Is there a common problem that will save me hours of time (& money) wasting? (probably not because search turned up nothing) I was planning on replacing the hub bearings and checking the callipers. I have had a good look under the car and can't see or feel anything loose in the steering. The fact that it only happens around 60 makes me think its a balance problem (but I'm no mechanic so thats basically a guess). Does the steering box itself ever pack it in? or is it more likely a ball joint or bearing? Any help I'm sure will save time. Thanks Grant

Have you found a good suspension upgrade? I know my ke20 handle's like jello with a ca18- looking to stiffen it up (cheaply :jamie:) Cheers Grant
