So the conclusion is none of the front components of the f80 will fit on xdrive? Is there anything that can be done to get more negative camber and improve the handling of a car with xdrive?

HPA ones are for front for sure. I think two of the Megan ones are for the rear.

Hi, so in conclusion, only the OE F8x front LCA would fit the F3x platforms, but the TS wouldn't fit?
And even without the TS, the benefits would still be there? |

Yeah, i have read those. But that was no conclusion on how this would affect suspension geometry as pointed out in another post here.
utenigma , he seems to have installed just the LCA. Any issues so far? Have u tracked with the setup? |

Suspension: Either BMW M Performance Suspension Kit or Ohlins Road and Track coilovers. Wheels: APEX ARC-8 18x8.5 ET38 (no spacers) Tires: Michelin Pilot Super Sport 255/40/18 The wishbones sounds like a modification that will requirement an immediate alignment afterwards before even leaving the premises. |

My reasons for installing these OEM parts were - steering lacked feel; - slow to turn-in and - soft outer shoulders of MPSS tyres were wearing prematurely. LCA (initially] and TS (fitted later on) are an OEM upgrade that sorted out all of the above foibles. After adding M4 TS's to pre-installed M4 LCAs - Geo - No impact on geo from having f8x LCAs pre-installed. Visuals - Front ride height up a smidge. Front wheels now sited back in the centre of the arch. Steering feel is same [IMHO] with LCA + TS as it was with LCA's only. 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 firmest adaptive 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/F3x TS. BP

Gentlemen, while I have had a few BMW's over the years and have done a ton of work on them myself, I am a novice at understanding suspension geometry. Sure, I can change out suspension parts but understanding the impact of subtle or major changes is not something I fully grasp.
So, given the conversation throughout this thread I wanted to ask the opinion given the following; 2015 335 M-Sport (5 hole struts) 225/40/19 tires on style 442 wheels w/36mm offset (soon to be fitted with Michelin PSS) What can I expect by swapping in the F80 LCA? Better camber, worse caster, alignment needed right? I don't track the car but drive aggressively both on windy roads and the highway in terms of straight line speed. Also, I see a few comments about wear to the outer portion of the tire being improved on PSS tires. The comments gave me the impression that the PSS wear excessively on the outer edge otherwise. I was about to pull the trigger on PSS and one of the primary reasons of switching away from the OEM P-zeros was because of the increased UTQG rating of 300 vs other tires in the low 200 range (softer and more wear). I just want to still have confidence in buying the PSS regardless of whether or not I swap in the F80 LCA. Thanks! |

Better camber for sure, increased caster unless you also fit the F80 Tension struts, you'll love it for windy roads. Alignment is more than needed, the LCA will completely change the toe so you can't even drive out. Quote:

Hi
So we installed the tension struts yesterday, using lemforder f30 bushings instead of f80 original bushings and a little help from a hydraulic press This has allowed the wheel to go back a little bit, really not much, but rubbing seems to be gone now

A few more pictures for those who are interested in this alternative way of using F8x Tension struts:
You can see the wheel remains quite a bit forward in the wheel pit, the other side is worse as there is slightly more caster.

For those interested I'm selling these 2 wishbones + 2 tension struts as I'm getting the car back to stock.

Haha no, but things are complicated with french road regulations, more than anywhere else in Europe and i can't really do what i want, so i'm considering changing to an F80 M3 base when i get a chance to get one at good price, e90's are nowhere to be found (many e92s but i need 4 doors...).
