My attack 20 is due for a swap, seems like there is hardly any options other than the Challenger, if a big wheel kit is put on Im guessing a 144 can be put on, am I correct.

I hated the A20 on my new 2005 M7. They didnt make the Challenger in 141 at that time (they did later) so I put the 144 Challenger extreme 2 .5" paddle with 3" drive pitch (for the M7) on it. Had to run the rear wheel adjustment way out but had enough to do the trick. What a diggin SOB. Later I put a 2 wheel kit on. 6000+ miles and no problems.
I see on tracksusa.com that they now make challenger extreme in 141 and 144 in 2.25 and 2.5. You didn’t say what sled you are putting it on but just make sure the pitch is correct. I thought the A20 had 3" pitch so you wouldnt have to change drivers.
I have a 2009 M8 with the Powerclaw and that would be the way to go IMHO. I love it.
