I'm dropped on KWs and I'm experiencing, as expected, and excessive inner tire wear in the front even at the "highest" allowable setting on the coils. I have Figs MEGA Control Arms in the rear that's taking care of the back tires quite nicely, but the front tires' wear is really unacceptable (very noticeable within 10K miles).

Anyone else on KWs or any other type of coilovers is experiencing this? any known remedies??

I'm going to swap my front tires for now (left to right), but I need a long-term solution.

what are you running for alignment?

I think the SPC Front Adjustable Ball Joint Camber kit, will be in my future shopping cart, when I need tires again..

I am employing the Lance Alignment and it seems to result in better wear (caveat: only about 6500 miles on the car). I also have the FIGS Mega control arms in the rear. Originally, I had Swift lowering springs with OEM shocks, but I recently replaced both with the HKS Hipermax M1 coilovers for the IS-F. I had another Lance Alignment conducted, but this time with "0" toe. It should be incrementally better. I've only got a few hundred miles with this set-up so the jury is still out on whether it results in extended tire wear. Lance's long-term tests do show a distinct tire wear benefit, though.

How much did you drop the front?

Joe z: will the front camber kit work for the isf. On the website it only says the is250/350.

I'm not sure I get your question... I don't have any special setup up front. Just the drop on the KWs

Ah! I forgot about these!!! That's an excellent suggestion!

I don't know the exact measurement, but it's a very moderate drop.

Good question for Joe-Z.... I don't think the upper arm is any different in the ISX50 cars than the IS-F. Can anyone else confirm??

But you did get an alignment after you put the KWs on correct?

yes... I got one right after installation and another one after I raised it some. I'm not too happy with how the numbers came out though... I got to find that sheet and post it on here.

I'm currently on BC Coilovers with about 0.5 inch drop in the front with 0 toe up front and after about 15K miles, I still have significant inner tread wear. Unfortunately I don't think the 0 toe up front is the remedy...Darshana S...

I will also be running this set up (bc racing coilovers). I bought a set of aftermarket wheels and tires from a forum member and the tires showed significant wear on the inside. He was lowered on tein springs about 1 inch.

I am getting this too, with Lances specs. Unfortunately if u are lowered this is normal, I would get the Figs Control arms for the rear and hopefully he releases something for the front cuz I'm not sure about the SPC ball joint for the front if your lowered.

Does anyone have the spc ball joints on there car? Is there any other options other then not to lower...

Does any one have the fix for inner tire wear issue when lowered.

ToothDoc

Out of curiosity, is it a toe in thing or is there some bump steer so when lowered toe is increased or is it just a matter of being cambered in too much or is it actually caused by caster angle so the edges are all worn first during turns? I'm fully stock and my rears wear flat but the fronts wear "round" so the centers are hardly worn but the both innner and outer edges are rounded out. I'm prettty sure it's not due to PSI.
