spring perches. i looked at it last night still in the box.

heres the link. since the powertrain is out of my car right now i figured it would be the perfect time to get rid of the heavy bulky stocker.

appreciate any input.
thanks

Now is the time to do it man!! Do some research before buying something. Hands down Maximum Motorsports is the right unit to buy, but its wicked expensive. Other companies actually tell you their k-members are not meant for street cars...but there are hundreds of guys running these on the streets. Who knows.

Also watch out for k-members that extend the wheelbase. Extended wheelbase=cutting front fenders usually. I personally like my PA Racing k, but my car hasnt been out of the garage yet. :(

x2 on Maximum Motorsports. All the stuff they make is top notch.

Agent47 makes nice stuff too, not sure if they have tubular K frames though.

Unless it is a drag car exclusively, I would run nothing but MM, Griggs, or Agent 47. Most of the others are junk IMO. Coming from a guy who only goes around turns though, so take it for what its worth (not much).

I dont see why it wouldnt be safe for the street if drag cars with tubular k's are pullin the wheels a foot off the ground then slammin back down with no issues

Two issues with that thought process ... most drag cars dont slam them back down (if done right ;) ) and drag cars dont see the side and shock loads that a street car does ... very different dynamic.

That all said, I've seen LOTS of cars live long lives with tubular k-members of most makes ... Whatever you do avoid Grannacopy, the rest are what they are.

I am not trying to say the thing will break the day you put it on, but after seeing them up close, I wouldn't even think about putting anything besides the three I mentioned on a car. They see ridiculous load paths through them, not just under cornering loads, but braking, hitting potholes, etc. If you want another part to brag about to friends I guess the cheaper ones are fine, which I suspect is how most end up on cars (and header clearance).

Yep now is the time to do it but like the guys mentioned, if its a true street/DD type I would want the beefier/engineered unit like MM. Otherwise, know the risk and keep up on inspection IMO.
