Stay away from the helix kits. Quality is horrible and and I can't believe the supposed engineering that went into it is any better.

 

X2 , I have bought a few of their bits and pieces in the past and they have been junk .
Another manufacturer to stay away from is Procomp if you have them over there .

 

Procomp I am familiar with from racing, and I don't run anything from them. Thanks to both of you for the heads-up on the helix stuff.

 

Helix is part of the Hoffman Group. Hoffman bought up a bunch of floundering auto accessory companies during the last gas crisis, took the products and sent them to China to be cloned by the lowest bidder, kinda the Harbor Freight of the auto aftermarket. If you want to see what is the problems and what companies are under the Hoffman group umbrella, google Hoffman group. (add complaints, problems, and/or reviews for detailed info)
