Title: Slick Screwing
Post by: digster on January 29, 2016, 10:58:33 AM
 As it would pertain to FED's. To screw or not to screw. Keep it clean guys. This has quite a bit of chatter with newer compounds and rims. Much of the info out there is for heavy cars and 12 to 14 lbs pressure. I've always screwed the rims down in the past. I tried a new technique recommended to me. Mount without bead grease and use Aqua Net hair spray to act as seating lube and glue. I did it at the end of the season and didn't get a chance finish running the experiment. Seems like screws bead locks are the norm. What do you run?

I run screws in mine 8 per side . There are guys out there that swear you don't need them but I have always used screws and will continue to do so . I am almost to the point of needing bead locks with my car . My mph is around 182 to 184 so it's almost time to make that step .

Run 5 screws per side running 7.0 @ 200mph  never an issue and would never consider BL's unless made mandatory

A while back I saw a slow motion video showing a distinct relationship to the size and location of the slick rinckles to the amount of screws. Any body else catch this?

Lots swear by them and lots saying not needed.I guess you could do some test hits w/o them and see if slicks move.Now if you are running tire that is narrower I can there could be safety issue.

I would run bead locks before running inner liners.Cost wise probably very little diferance,weight wise beadlocks lighter and add in ease of cghanging slicks.JMO

I remember reading once at around 8psi and up you shouldn't need screws anymore. I couldn't tell you if its accurate.

Hard to run beadlocks if for nostalgia purposes you are running a cast wheel. The wheel should always be 2" narrower then the tire tread so it stands up straight  on the burnout. Having the wheel same side as the tire pulls the beads together as they stand up.

 True on the air pressure deal and most tires now like the higher pressure because compounds and tracks are better

Not to distract the purposeful tech talks here, but someone can make some money by selling the title of this thread as a slogan to the K-Y jelly company. ;D
