12mm spacers, seems a bit much on front

[kitkat]

I’ve got a very slight vibration on the steering wheel at circa 100mph. I’m running 12mm hub centric spacers. Not sure if I always had this or not. It’s not bad, but it’s there.

Is there a correct way to install wheels with hub centric spacers, to ensure they are properly/perfectly centred? Any opinions as to whether a hub centric spacer can cause this sort of issue?

I will get around to testing without the spacers, to see if it makes any difference (live in an apartment and don’t have car tools to change a wheel ATM).

Make sure there’s no debris or rust buildup on the hub mounting surface or the lip of the hub. Start pattern mounting but use two sets of torque values — a lower one to center and then a final one to torque to official spec.

I just installed 12mm hub centric spacers from GRP and lowering sleeves. Also did CT carbon full kit and it looks awsome. Prior to this installation, I also did 3 rd cat delete with miltek valve control and eventuri Intake. So far no issue whatsoever just happy with the result.

LOVE the carbon on the White.. Looks sick man.. Love the whole car.. Congrats. I wish I like carbon fibre but I just don't.. I am hoping somone (GRP talked about it) would make a wing or rear lip spoiler in the same black as the black pack or able to paint it.. I would def buy that.

I got the wheels balanced and that resolved the slight vibration I was getting after fitting the spacers.

I’ve now lowered it a little by just moving the shock circlip and am happy with the results (10mm difference on the shock). Not a big drop, but enough IMO. The roads around here can be pretty terrible, not sure I’d want it much lower, or firmer than it is now.

Using this approach will actually get your a softer ride

I believe spacers (or higher offset wheels) effectively reduce the spring rate a little.

Many thanks for the tip/info about the suspension circlip modification

Are you using the standard wheel fittings?
I have yet to fit the GRP titanium motorsport fittings. Apparently you torque up the threaded bars which stay on permanently which hopefully will ensure the wheels are perfectly lined up after fitting.
Previously after getting what I thought was a balancing issue after going down a road full of potholes I removed the front wheels and refitted using lining up bolts and the issue disappeared. Also good to clean every as suggested by Kitkat.

No, I bought longer bolts, 45mm if I’m not mistaken. 32mm as standard.

The spacers used on the Emira are not the type that bolt to the hub, with additional bolts to the wheels. The hub centric feature on the doacer, should avoid any misalignment.

The small issue I had was a wheel balance issue, Lotus checked the front wheels and had to adjust the weights a little. After that, no more vibration. TBH it was very slight and was likely always there, was just a bit more sensitive to it, after adding the spacers.

I have hub centric spacers as well but it’s still easier than you think to not line them up 100% which can have an effect. The lining up tools are pretty cheap and as long as all faces are clean gets it perfect every time. My mate let me use his and I realised how easy it was to change a wheel.

Ok, wasn’t aware such a tool existed. Something like this?
