anyone running the alta lower control arm mount bushless things ? and how long for and do you like ?

 

If you are referring to the Alta PSRS, I have a set installed on my 04 MCS that is mostly for track use. The only issue I have had is that the set screws won't stay tight and caused an annoying rattle. A bit of welding made that issue disappear.
In terms of performance, they really stabilized the front end as advertised. I have no regrets with this purchase.

 

i too, question your question. i have the alta PSRS if that is to what you are referring. i love it. i have a pretty aggressive alignment and the car was "twitchy". with the alta PSRS, the car is much better in a straight line or high speed sweepers. i've had it on my car for almost a year (5 track weekends). if you want to go fast, you need this! (or an additional 35 weekends of work). install costs will be about 2X the cost of the part unless you think that this is a diy......

 

I too am tempted to put the PSRS on.I am desirous of crisper turn in and more stability on high speed sweepers.Did it cut down on the front end rolling from side to side?I just had my dealer look at the front suspension while the brakes were being replaced.He said that the soft sidewalls on my Khumo's were creating the sensation I am speaking of(RIGHT!)AS if the run flats were superior-whatever!Are you running any other suspension upgrades?

 

when i went from run flats to reg. i felt the roll right away . but it felt better . no push in tight turns . the run flats tended to under steer . a strut bar from mj7 fixed the mushrooming but some understeer is back . but not like with the runflats . the psrs sound good but i suspected the set screws would back out .

 

the PSRS is one mod that has helped on both the track and the street on my car. it doesn't help turn in, but my car already turns in exceptionally quick. i have quite a bit of suspension work.....Spax coilovers, RDR adjustable camber plates, 19 mm rear sway bar, pro-grid drop links (front and rear), m7 USS, RDR adjustable lower control arms. upper control arms are going on tomorrow. with this equipment and a pretty aggressive alignment (-2.5* front camber slight toe out, -1.5* rear camber 0 rear toe), the car was almost turning in too quickly. while on the highway, i would go over three lanes if i looked away. it is much better behaved now. on the track, there are many places that i can now drive much faster with more confidence. Beckett's Bend, at Sebring is a long, fast left-hander that can be run flat in a MINI. one steering input at the beginning of the turn, then hang on. i usually exit that turn at about 113 mph. i was able to do 102 mph with slicks on a wet track. the PSRS makes this a much more comfortable event. this wouldn't be the first suspension mod that i made, but it becomes almost necessary after other work is done and speeds are higher. my front end doesn't roll side to side!

 

I'M NO RACER BUT THE STOCK LOWER BUSHINGS SEEM WELL LIKE CRAP . SO WOULD THE PSRS BE DOABLE ON THE STREET OR ARE THEY HIGH MAINTENANCE?

 

Either the alta or Powerflex. I used Powerflex without any problems for two years and about 78K miles - commuting and on track.

 

I just re-installed the powerflex bushings over the weekend because the stockers I installed last spring wewre leaking. Love the responsiveness...the ride is still a wee bit harsh with stock struts. Over-all, a job that doesn't have to be done again. Replaqced the swaybar bushings too - these were pretty worn after 113K miles

 

herbie_hind: I may have missed something. Are you referring to the REAR trailing arm bush lockout product we didn't release yet, or the PSRS for the front? I want to help, but missed something! Thank you!

 

ok. i'll bite! tell us about the "as yet to be released" product. or pm me if you need a beta tester......

 

i was referring to the psrs . it seems like a good alternative to bushings, but the set screws are a concern. maybe a notced line or tck weld would do it ; but then it gets into the " why all this for the street " catagory .

 

i haven't had any problems w/ my set screws. even if i do, at some point, the solution is already at hand. if this is "too much work for a street car", the dropping of the front subframe required for installation will definitely be too much. maybe this one isn't for you. i'm glad that i have it.

 

Nice thing about the Powerflex bushings is, if you have to remove the LCA, it will simply slide out of the bushing. There are no set screws to worry about.

so you have two options that according to the folks inTexas, work and feel the same. They use both.

 

now that's the lazy man special i want
