I'm racing my S1 locally at my club's indoor carpet track in the 17.5 blinky class. I use Sorex 28R pre-mount tires and 2S lipo packs. My car handles great and I took TQ and the A-main win on my first outing with this car beating several guys running sedans that cost much more.

Will this may have to be my next car. I just bought a TC6 as my first on-road car for carpet this year. But I do like this car I just may need help with set-up on this car.

So tried running 5000wt in the rear diff and the car seemed to like it better than the 3000wt. The r1 diffs are truly different then any other in terms of oil that can be used. If I put
5000 wt in say any other diff it would be way too much.

Gotta echo Jeffs comments there, I finally got round to putting some power in the car yesterday, (10.5 boosted) at the warm up meeting for our winter nationals, the car handled the power perfectly with my set up from 21.5 boosted with the exception of upping the diff oil from 3k to 4.5k
If I had access to 5 or 6 I would have tried that if I'm honest,

The A main was really tight with just 10 seconds covering the top 20 and 5.5 covering the top 10... Luckily I scraped 10th with a pretty average run but was really happy with the car, just my driving and a severe hangover causing the problems haha

Hi Jeff,

Which one of your setups are you running? Are you still widening you car at the hexes? I want to try some of your setup changes this weekend.

Thanks...

Loose as you can before they skip/slip at all. Note they will loosen up and stretch a little after running the car a few times.

I race with Jeff, and before he replies himself, I can tell you that our club just changed to a new layout which means less grip from the carpet itself than normal. I believe he is widening the car in the suspension mount themselves. I believe he may not have had any shims at the hexes this race. When the grip builds back up then the shims will be needed again. We usually have 75 to 95 entries so it won't take long

I got some of Jeff's shims to place between the hexes and the rims on my car, they are really nice!!! He did a great job on them.

Does anyone know if the Spec-r (SPR-R1P303) steering knuckle and rear hub is an exact fit for the Xray T2/T3?

Looking at the manual... I can't figure out where there's both a 10x13x4 and 10x15x4 bearing that goes over each side of the diff/spool outdrives. What's up with that?

EDIT: Nevermind, I see now that the 10x13x4 is just a spacer.

Trying to decide weather to get an R1 over the S1 just got harder .. S1 is on sale for $99 at RC mart.... I dont mind paying more dosh but the S1 seems insane value.
All of my driving will be asphalt track. I thought I was set on the R1 but its a really tough choice!

Under $100 is a killer price and the car is very capable. On asphalt, I believe you want a slightly more flexible car anyway so having graphite for outdoors may not be ideal anyway.

Might be worth just going for the S1, you can always buy a ton of stuff for it to make it into an R1 if you really wanted and I doubt it would cost more if you can get the S1 for $99.

Perhaps price up an S1 with some upgrades and see which one you would prefer to get.

Also, just noticed they now do a carbon bumper holder.
