Any of you guys had any problems with the nylon screws that hold the rotor on? Three nights or so and one screw was out and the other broken. What did I do wrong or should we just go to the steel screws? Thanks

you can use steel screws..biggest prob with the plastic screws is people over or under tighten them..all we run on all of our cars is dui and never had any probs..yet...LOL

The first race with my new DUI stuff the nylon screws broke which also caused the rotor to break. Go with the steel.

are you sure the cap is on straight, and rotor button not hitting? also some people install the spring and rubber bushing wrong under the coil. there shouldnt be enough pressure on rotor to break screws unless something is wrong..

may need to check end play on distributer..

End play was good out of the box just by grabing it etc. When we found the screws were haywire the rotor contact was bent to the left and some of the plastic broken. End play is in excess. I found that end play should be between 8 and 10 thousands. We will reshim but I don't think my driver wants the nylon screws back. I really don't believe I got them tight enough and of course being cautious not to break or strip them out when I put them in. Wish I knew what the torque is supposed to be on them because I could do that too.. Thanks guys on your comments.
