Clicking noises on full lock

[Nathan Pitman]

Is this normal? I get click click click click from the front wheels when manoeuvring at low speeds on full lock.

yes, TADTS

[Nathan Pitman]

TADTS?

[Gashead1105]

They all do that sir

It's the Anti Ackerman steering geometry. Means they corner better at speed but makes a tyre skip at full lock, more often in reverse.

Yea I hear the tyre scrub and understood that was the cause of that... just wondered if the clinking/pinging noises were also due to the same thing.

Is that TADTS for S1 as well? Mine has always, but thought I would ask given the post!

If it is scrubbing the tyres then as above Ackerman Angle. This applies to most Lotus' including the Evora S1.

If it is actually clicking, then likely that there is dirt between the wheel and hub, so need to take the wheels off and clean the surfaces. Had to do it to mine last night.

Mine started to do this on a trackdays, the dealer looked at it under warranty, as said above, the factory fix is to remove the wheel and clean the hub, mine is quieter than it was, but still quite noisy and is going back in to be looked at again.

My GT-R did this - wheels off, clean and grease the hub = quiet

You might need to get a very fine sandpaper and give a light going over to get the surfaces absolutely smooth and clean. 

Easier to do it myself than take it in. Mine first did it on the Isle of Man, so also when brakes were in heavier use.

Thanks for that, Colin! Will be cleaning hubs when I get home.

Probably explains a slight wobble under braking, too.

Thank you guys, I'll try cleaning the wheel / hub interface.  My S1 does this when taking left hand corners at ~20mph+.  Going to the right or slowly round a car park no problem but turning left on a twisty B road and I can here some clicking noises, think its coming from rear right wheel.
