What a great value, I have to order one. For those of you that have built and run the car, did you go straight kit build or did you get any of the R1 parts as hop-ups?

i built it straight no upgrades, if you start to up grade, then the r1 is a better price, the car already has all the go fast bits, universals, geardiff, spool, all you would need are some djc as the front wheels lock up at full turn, not needed, but nice, def a great buy I like it so much I ordered a r1 to try out against my t4.

I like the panaracer ones, but I can never seen to find a place that has them - best I can do is leespeed ones, but have to get them from Hawaii in sub-90 sizes

What is the pitch of the pinion gear? It may just be a senior moment, but I don't see it anywhere.

Stock is 48p like 84t or somthing. I kimbrough pancar spurs. I've used as low as 88 which is as low as you would want for 17.5 maybe 21.5 depending on type of motor and layout.
Tq sells pretty much everything you could ever want for spec r and some of the best shipping around. Might as well go with the source =]

I haven't melted too many. 1 so far, but having said that I will probably melt another 2 next week because I said that.
I am only running 3.91 FDR and a 52.2 rollout

changed to xray o-rings, and it fixed the problem.

did a few too many donuts, the orings expanded and another notchy diff. The shims may warp too, so check that if youre just replacing the housing.

I finally put some work into the diff, scraped off the melted plastic, smoothed it out, and put smaller size orings so they wont cause the shim that sits on the outdrive to spin.

Only weakpoint in the car thus far.

I had thought that the diff was pretty good in the spec-r. as long as the prep was done to get it together right

I built a s2 for a friend yesterday. Overall, pretty decent kit and should be great for club racing. The only issue I had was that the big, thin black band that supposed to seal the diff, doesn't go on, so I left it off. Overnight, no oil leaked so I think it should be fine. The plastics are hard to screw into but manageable if you have a good set of drivers. The chassis feels nice and stiff, little slop, even the ball ends were pretty good (although hard to thread on)

you definitely need to buy some shims for the dif to save it from a 4.5 and id likely run a heavier dif oil than you might in a stock car. i was running 3000wt in mine and it held up fine, shimmed fairly tight but not bindy.

this is the older non HD dif.
shocking to hear the larger gets in the hd would die so easily but plastic is plastic i guess and a 4.5 is a monster torque machine lol.

some good news though;
Irocc had its first club race of the season on ashphalt last weekend and there were Two S2's and an R1 in the Amain.
Blake ran his S2 for the first time and set TQ which isnt terribly surprising but it really goes to show he wasnt losing anything going from the absolute top of the line, the bottom.
My R1 with S1 chassis plate Managed second overall qualifying in a pretty good race with blake in the third round of qualifying. I actually lead that race on a tq pace, but fell off a little bit at the end. i still noob and make mistakes heh.
being tailed by someone who doesnt make mistakes is more than a little intimidating lol.

we built a rental ride using the s2 platform and it ran flawless all day. more interest has come up for the kit within the club as well. I have a feeling specR has won some allies here on the island.

racing this weekend. Hope i can get just a little more from the R1 but if it aint broke, dont break it lol. car had messtons of traction and very responsive. pretty much running stock settings but i doubled the upper arm shims on the middle hole. might play with spring rates in preparation for speed weekend. and practice a little with my R1prospec mod car.
