m4 tension struts to go with lcas
Fitted up a set of m4 tension struts to go with the lcas, will post more info and spacer sizes as I complete. I had to order some spacers, once I do final install and testing I will post the part #'s. Drove a bit, no conflicts.
So far, moves wheel back 1/4 of an inch, correcting some of the lca forward movement. does not seem to effect alignment, will check later when proper spacers are in. much better bushing, much less movement. Also there are uniball kits for this joint, I will check that out after testing stock bushing on track. Steering feel is more communicative, esp. braking. |

This is very interesting. Does the wheel still get pushed out (toward the fender)? Can you label the tension struts? I don't know what that part looks like.

Also curious about other affects besides positioning. |

How big (what are your front offsets)?

ok, installed spacers today, To keep the tension arm in the same location as stock a 2mm spacer is needed on the outside, 15 mm spacer is needed on the inside. hole dia (id) is 12mm for the spacers.
If I am lucky I should be able to test drive later this week, maybe align early next if not too far out of spec. If all is well and schedule clears, I will test on track on the 29th. I have a feeling this should make a huge difference in steering feel, as the bushing replaced was a massive hydro bushing. Last edited by Pparana; 04-18-2016 at 07:17 PM.. |

Woaw
![]() Only problem I have is the spacer we will have to add on the arm ... Will the structure of the arm and the bushing be strong enough? I remember, when I did the job on my E82, I had to pull the LCA in the subframe with a mallet :P

aluminumspacers.com, however I may look for a larger od. Material wise its no issue, just in my head.
Drove a few miles, def needs an alignment. Struts added .2 toe out each side, and I think some more neg. camber. I have camber plates and coil overs so your mileage may very. So far so good, feel is much much improved. I actually know what and where the tires are. Prob. similar to the m2, since using same parts. Have the car on the rack, doing a few other things, maybe get it out this weekend if I knock out my chores. |

This is amazing news. I was hoping someone would do this and key everyone else in on it.

From what I remember you had all these and rubbed because m4lca pushed you forward too much right? Maybe I'm thinking of cloudxi though. |

If it's completely working, that would be fine. We will have the solution for the front axle and the rear axle too thanks to aftermarket arms!

These tension struts are a partial solution to the forward wheel movement from F8x LCAs, but 1/4" is only ~25% counter to the effect from the LCAs (citing Bee Pee).

finished it up today, did an alignment and some other maintenance.
Honestly I had put coil overs on the car and taken it up to sebring and beat the hell out of it a month ago, so unfortunately it got knocked out of alignment up there and everything in the suspension settled. So my numbers may be off a bit on the drop ext, I think you loose about 1/2 degree of castor gained by the lcas, gain .2 camber and toe out slightly. The car feels better to me, more connected, some people, who like a plush ride would not want these. The ride is stiffer, but not as stiff as my 991 or f type, but the ride is also not as refined as either of those. There is better control of the brakes, as the feel is lost in the stock hydro bushing. I can feel the tire slipping now while threshold breaking, and you feel the road reflectors ext when driving. All and all, if your car is for mixed track, or spirited driving I would say go for it. Not sure how the front would feel on the stock suspension with these, but worth a shot. |
