10mm front spacers.

Post by Torquey » Sat Dec 22, 2018 2:50 pm

Hi, was contemplating fitting the m3 lca modification to my 15 plate 135i to help sharpen the steering and make the front feel more planted. I spoke to birds who fitted my b1 series suspension and they recommended just fitting 10 mm spacers to the front, has anybody any experience of this?

M4 LCA's are the proper way to do it, as they gain you camber and better bushes. Spacers are a cheapo bodge that will ruin your scrub radius.

Thanks for reply Marco. Would Cotwold bmw be the best place to purchase m4 lca’s, any idea of cost?

Most people buy Lemforder arms (who supply BMW), rather than paying BMW's mark-up.

Something like https://m.buycarparts.co.uk/lemforder/9664290

Ok great, thanks for your help. So after getting lca fitted I’ll need to get the wheel alignment done. What alignment settings do they need to be set up at if that’s not a stupid question.

Same Toe angles as stock, assuming you're happy with that. I like mine almost parallel for a sharper turn-in, but it makes them a little twitchy at speed.

Camber and Caster aren't adjustable.

They are M4 LCA's.

Don't forget the ball joint from an M4 Xenon Reg rod and M6 nut, per the M-Lite FAQ Sticky, post 5

I had the M4 lca’s fitted today, cars so much better now, turn in and the grip is fantastic now. Thanks Marco for the advice.
