Visuals - Front ride height up a smidge. Front wheels now sited back in the centre of the arch.

Controls - Steering feel - too early to say but doesn't feel any different to F8x LCAs only. Mpbbk Brakes feel more responsive.

NVH - up by a v small amount but hardly noticeable to my old ears

Remus midpipe also installed between my HFC DP and MPE - read this thread http://www.babybmw.net/forum/viewtop...68909#p1189851.

Jay (owner of Crown Classics who did the work ) was very complimentary both about how my car drove but also about Remus midpipe fit and finish. I will be using these guys again - very good service and attention to details.

Excellent!

I just installed mine last Thursday night, and I have to say that my impressions mirror yours 100%

More thoughts:-

Steering feel is same [IMHO] with LCA + TS as it was with LCA's only.

Turn-in feels quicker although might be placebo + weather isn't great so opportunities to load up outside tyre are less than in the summer.

Braking - much sharper as one might expect with firmer TS bushes but this is marked improvement esp with my setup MPBBK, M4 sport pads and SS hoses.

NVH - slightly more in comfort but no change in sport+ mode - I think firmer damper setting is better suited to my aftermarket springs.

No regrets at all and TBH I'm happier now that I have matched LCA & TS as opposed dissimilar F8x LCA and F2x TS.

So your LCAs and TSs are both F2x or both F8x?

same as rwd except you do not need to remove the carrier (no axle)

zipphreak · 12-15-2016, 05:52 PM

And if you try removing it on a RWD you might have issues

Good references tho !

casualDIYer · 01-01-2017, 02:45 PM

Anyone with 17 inch wheels run the m3 lcas/ts setup? For the winter I actually run 16s but wouldn't mind going to a 17 if I did this mod.

I have the LCAs but not TS and run 17's for winter and track use. I don't have any clearance issues.

Yes my track setup is 17x8.5, 16" wheels clear brakes?

Thanks for the info. I saw a set of 17 inch replicas. Now I have an excuse.

16" do clear the brakes. It's actually written in the manual which size wheels will fit the car and 16 is on the list. I do not/not have the M sport brakes. The nice thing with 16 is that the profile is so big it's almost impossible to curb a wheel.

You're on factory dampers/shocks or after market coilovers?

Yea, factory shocks and springs. For track, wheels are 17x8 ET 42 Kosei's w/ Hankook R-S3s - 245/40. For winter, 17x7.5 ET 42 Anzio Turns (they are cheap and soft - I've bent 3.) w/ Dunlop Winter Sport 3D.

Update

Finally got the car back to Hounslow Tyres into their Hunter Hawk Eye wheel alignment rig

First photo blow was previous alignment result with H&R springs and M4 LCA only.

By comparison, 2nd photo below is results from this mornings visit with Birds B1S springs and M4 LCA and TS

Camber and castor unaffected by adding M4 TS.

Guys had to make some tweaks (one trackday curb too many

ops

and the car feels far better for it.

BP

UPDATE # 2 23/1/17:-

Done a few miles over the weekend post alignment solo mio - some observations :-

NVH - any increase since fitting M4 TS has gone - same as with just M4 LCAs;
Steering feel - weightier and more responsive;
Traction - most noticeable improvement - seems to squat less [although running map 4 just now] - even on MPSS in ho-hum conditions - winter tyres going on tomorrow

Wasn't complaining before TBF and even happier now. However, could all be placebo but for £50 all in at a local tyre shop am I bothered ??

Should have got this done sooner !!!

jmwilson125 · 02-16-2017, 08:44 PM

So its:

31106797237 hex screw with collar for LCA to subframe
31106795930 hex screw with flange for tension strut to subframe
33306787062 combi nut x2 (optional, but advisable)

from what i can gather on real oem

Hey guys Im trying to get every part ordered to do this in the next couple months. Does anyone know the quantity of bolts and nuts needed. I ask because I do not have easy access to check.

31106795930 hex screw with flange for tension strut to subframe x 2
33306787062 combi nut x4 (optional, but advisable)

to have new mounting hardware for both sides for ts and lca

The combo nuts are nylock so its advisable to replace them. The nuts for the hex screws with flange and collar (on the subframe side of the install) are 33326760668 and you'll need 4x of those too.

Most important is to get the new bolts/screws though.

I used a bmw dealer that had an e-bay store. ymmv

casualDIYer · 03-18-2017, 05:00 PM

Looks like nvh and possibly other issues seems to be part and parcel of current camber plate offerings. Time to go with the lcas and ts mod come April.

One question: Did anyone who did this mod need a 1mm spacer for the LCAS? One poster on another post mentioned it but I didn't see anyone else say they needed it. Curious as to why that was the case and whether I need it as well.
