Officially have the alignment done... my friend who tracks his 2 weekly and owns a shop did it with the specs below, freaking insane overall!

The bumps for the lane separators are a bit more pronoun but hard bushings do that, my friends c43 OEM is just as firm on the bumps.

Regarding rub. I roll the fenders as I was cutting the 235/40/18 MPS4S with et40 18x8.5.. lowered their spacer 3mm, so et42 now, and still super close to rubbing fender. Wheel well rub is massive on large bumps which dip the front suspension. Not dangerous and lining seems intact but has tire marks.

Overall, even with the fitment issues, I'd do it again.

Alignment:
Front
Camber 1.6 deg / 1.8 deg
Toe +0.05 deg each side

Rear
Camber 1.8 degree each
Toe -0.16 deg each side

Take my word for it, this alignment is heaven! Car straightens out on turns super smooth! And makes it even heavier and agile than the lca+ts makes it. The highway jams left and right are x2 more planted.
Negative Toe in the rear? Doesn't it feel very nervous and prone to oversteer?
Personally, it feels great. I was very skeptical... I used to run Dinan spec alignment and I felt that made the drive more nervous feeling through some curvy roads at times. Also feels pretty good doing higher speed, full throttle, maneuvering considering the OEM shocks and Dinan springs.... also super cool, the car wants to go straight always so it feels really good coming out of turns and straightening up, very natural...

Damn, if some of you guys are just wanting to reduce shoulder wear and increase front end grip, simply go with a set 18X8et 40-43 wheels. You can fit 245/35s up front with no clearance issues with the strut or wheel liners. I'm running Alutec Drive 18X8et43 and with a square 245/35R18 MP4S tire setup. The increased grip of having nearly a 1" wider front foot print compared to the 225/40R18 is pretty significant. Also, the front shoulder wear that was common to the 225/40R18 is long gone.

I have both 245 fronts and M4 LCA and still get shoulder wear. :

Is this with lowering??

I'm on 18x8.5et42 w 235/40 PS4S and rub the front bumper and lining lol (not fender after a roll).... I'm gonna do 235/35 PS4S next time but the LCA+ts really screwed the fitment goals. Also i have a 0.5" Dinan drop front.

I guess the 8" wheel makes a huge difference...

Tire shape / compound and square set up are required if stock suspension

The tire shape/ compound makes a difference. I am square now with 235s on all 4 corners which did make a difference. However I also am running Hankook R-S4s. When I ran MPSS 245s on all 4 corners I still had significant wear issues. (Corded a front tire)

Thanks everyone for the great info!

Can anyone confirm if the below Nut is needed for the upgrades?

"(2) BMW Tension Strut Nut - Genuine BMW 31106767496 (supposedly this one is welded to frame so not needed, will confirm)"

Can some of you give recommended alignment specs for a car with LCA & TS that is NOT lowered?

I saw some people post alignment specs but I think most I've seen are lowered.

Thanks!

Well here's my alignment, I'm pretty happy with it.



On my relaxed drive home from my alignment shop, I immediately felt the loose electric steering improved and is much more responsive now. I also get more feedback from the road, less numb.

Did you notice much NVH increase with the LCA/TS?

Thanks,

There's definitely new NVH as a result of LCA & TS. I'd say it's not for everyone but for me the sharpness of the steering outweighs the noise and harshness of road bumps.

What are your wheel/tire specs on stock suspension? I want to go the LCA/TS route and also debating buying 18" wheels (running Style 380 17" now). This might be necessary even, if my 17s are too small to host the upgrade; still researching this but also want to know my larger wheel options without rub. Thanks!

I've got Apex Arc8 18x8.5 et38 - 235/40 (Michelin PS4S) in the front. I'm getting rubbing on the outside of the tire on medium road bumps. I need to look into rolling the front fenders but I'm not entirely sure if that will solve the problem. Fitment is tough with this car. Apex wheels recommended this wheel and tire and told me the camber (~-2°) of the lca & ts mod would allow for this fitment but it's not that simple.

That doesn't make any sense.....

when you fit the M4 TS+LCA, you get camber by moving the whole wheel hub strut assembly outwards (pivoted on the top strut mount). Doing this can only make fender rub worse.

However, if you corrected your camber with adjustable top mounts, then that would move the top of the wheel inwards relative to the bodywork, giving more clearance.

Summary: the M4 TS+LCA will not improve wheel to strut clearance and will make wheel to fender clearance worse in every case.

I agree, I got some bad information from Apex. I thought I made that clear in my post.

I've still not rolled the fenders but I'm hoping it helps with the rubbing that I'm getting now. Otherwise I may look at getting some Millway camber plates.

hmm i also have the same Apex wheel specs but with 245/40 tires for my F30. I'm dropping my car off next week to get the F8x control arms and tension struts installed. I am still on stock suspension also. Hope I won't get too much rubbing...

Yes, the adjustable tension rods use spherical rod ends:

Hi guys, i need some confirmation before fitting the LCAs and TSs.

My M235i is on stock adaptive suspensions ( stock springs and dampers ) with 8Jx19 ET36 wheels and PS4S 225/35/19.

Will i be for sure at 100% without any rubbing or similar problem ?

You will probably need a slight fender roll. Maybe, maybe not.

I'm with 18 8J et40 with 245 width tyres and it rubs. OK you are on narrower 225's, but the 19" won't help and you are 4mm more poke with et36.
