They aren't too cheap at $799 per pair.

Are they legal for SM class and would they be helpful for autocrossing?
No question they would be good for track.

Anyone already using them for autocross? What do you think?

 

Also Interested to see who has these and how they hold up on a street car. Also if they can withstand the winter on a daily driver.

 

dig through the old threads some had a set of tubular lower arms fail on them. I can't recall all the specifics (or whose they were) and I'm not trying to crap on madness' product, but I'd be weary towards buying a set.

Especially since they are chrome moly steel, Chrome moly has to be welded in a very specific manner or the joint becomes very brittle (why SCCA and NASA kinda shy away towards suggesting its use in roll cages, its allowed but not encouraged). That and I don't see the 5lbs total weight savings worth the $800 they cost, buy a new set of tires and go to an evo school, that will make you faster

 

i had to get a new set, so i got the madness arms. The handling they provide is amazing, however, for the cost, i would probably say put alta psrs in if they are allowed, if not, they are expensive, but man, the turn in is ridiculous. I havnt had my on the autox yet tho, but have tracked them. I took them for a run in the twisties (really tight twisties, is only it was an autox run), and they were very nice, no increase in noise that i noticed.

 

I think the Madness front control arms are stong enough.

Any weight savings is good.

I think it is legal for SM class based on rule 16.1 E

Suspension components are unrestricted as long as they use the original attachment points. "Suspension" includes shocks and struts, control arms, steering knuckles, uprights, etc., but not tie rods, steering racks, or subframes

 

Something of concern.

The front control arms are designed by MINI with some built in safety in case of crashing. The arms will absorb some of the impact and spare damage to the undercarriage.

Since I use my MINI for daily street driving I will be keeping my stock front control arms.

 

Exhibit A:

 

Exactly.
I've seen several front crashes resulting in quite a bit of front suspension damage and pretty good protection for the occupants or driver.

I like the safety design of the stock part and appreciate it. Parts are easy to replace.

 

I ahve heard horror storys of these breaking

 

Of what breaking? Madness Control Arms? OEM? Or those that belonged to a DIFFERENT vendor?

 

LOL the front arms from vendor M# were the ones that failed and were reported on here.

 

Myself nor George have ever heard of his Madness arms failing....

 

I'd buy them if they were $400 a pair.

 

the madness arm

 

The arms that were failing were made by a different vendor......something like N6 O8 or something in there

 

I don't think the Alta PSR's are legal in SM either are they??? I think you can change control arms, but can't change the material that the bushing that was used in OEM equipment. IE:Bearing or solid mound instead of a Rubber bushing.

I thought those stories were of rears failing, not fronts. Any ideas?

 

Actually both.............

 

Any posts about it. I searched and couldn't find ANY.

 

The member who had these fail on him was banned and all of his posts were deleted.

You might want to email Jan at RMW and ask him about these arms.

 

rustyboy had them fail........?

 

Jan did (the M7 ones)

 

Not me.

Talking about Jan (Before he was a vendor again). He used to post on here but was banned a few years back. He was later allowed to rejoin as a vendor.
