GY 2070 and 2078
« on: May 29, 2022, 12:54:05 PM »
Looking at new slick options. In GY selection two look like possibilities.  2070 and 2078. Wondering if any here have tried either/or results and thoughts on them.

Use to be you could try a cpl different setups,sale off later and lose a little with cost increase you need second mortage to buy 2 or 3 sets of tires

I ran the D2070’s on my car for years had shake issues and when it did t shake my car would walk down the track not really that straight.  Last year I switched to the 13.00 33.3 -16 M&H tires which are currently impossible to get. What I can tell you is with these stiffer side wall tires my car runs perfectly straight down the track.  I recommend a finding a stiffer side wall tire then the D2070’s.  My car runs 6.47-6.70 SBC with a 10” 2 disk and B&J 3 spd.  I run with another FED powerglide car he has the MT big bubbas which I think are ugly on a FED (my opinion doesn’t matter) but it works great for him 6.90-7.0’s no shake

The big bubbas are very popular with RED guys,not sure I have enough power to pull that tire on FED. I know FED's normally get down track better with less tire than a rqual power RED needs. Being a bracket car I have to be more concerned about consistency than fast. As life long tuner of heads up not putting fast first and foremost is hard as xxxx.

I've seen a lot of people have good luck with the 10.5 or 10.5W slicks on their FED's.
