Some more diff tips to add:

I tend to set mine at only 1/8 turn out to start and then maybe loosen it a little after I know it is seated from a run on the track.

Try a bit of blue loctite on the threads of the thrust screw as some extra insurance to keep the screw from loosening.

I ran the same diff all through the Reedy Race and for 4 additional club race days before I finally rebuilt it. Same parts, just new outdrives...clean and re-lube and it feels great again.

I ran my TC5 all day yesterday with a 3.5 on Take off's with virtually no tyre wear, they only just look scuffed in now, as for high wear items , Diff out drives, and a few of them, we went through three diffs yesterday between me and a mate , Jeff can get them at Trackside RC cheap too, As for shock oil I was running 40wt and had no problems, I just had to learn to drive the 3.5, Try Leonards setup for the Sunny coast track it is a real good starting point, I ran a different setup for my first 2 runs and the car was poo, pushing, taily, no turn in, then changed heaps to get it to Leonards setup and it was a completely different car..

the standard diffs work perfectly fine with low wind b/l motors (3.5t and 4.5t) as long as you take care when building the diffs.

1. make sure the diff plates are cleaned with motor spray
2. place 4 small blobs (equally spaced) of silicone grease on the outdrive - d-ring area
3. make sure the diff plate is facing the correct way (sharp edge towards the outdrive -facing down away from the pulley)
4. build diff as per instructions (diff spring precompressed/diff nut securely held in place)
5. make sure the diff is tightened properly



Hope this helps you guys out.

After Me munching a diff and my mate next to me doing one , Leonard gave us this hand piece of info,and I rebuilt mine at the track, and had no problems for the rest of the day, Thanks Leonard

Good to see that Sean Cochran won the ROAR paved on road stock class today with the TC5! Nice job Sean! I believe there were 3 TC5's in the Mod A also.

I'll second that! I got to watch some great racing Sat. and Sun. and meet Brent, Kyle, and Kevin. Got some tips and from Brent and Kyle and witnessed first hand what these cars are capable of doing on a asphalt track..WOW . Brent said he would post the setup sheets for our track...I'll be watching for those, also would like to see the final results for Team AE when you get a chance... had to leave before the day ended.

Great group of guys and great car for anyone thinking of a purchase...you wont be disappointed! Keep up the good work team.

Internal is 2.5 so 78 * 2.5 / 19 = 10.26

Default Loosing grip while using Spool

I melted my diff, due to lack of spares (like anyone else, i think), i had to build a spool.

With two diffs the car was always superb, but with the spool in front, i always lost rear grip while entering corners off-power. Is that something others have also recognized? I always thought that a spool will reduce front grip overall. BTW i raced on high bite carpet with rubber tires...

I took away rear anti-rollbar, used softer rear springs. Car was a bit better, but slower and more difficult to drive than before with my two diffs.

Has somebody an idea what i could do to bypass the time without the
alum.-diffs?

Thanks for your help guys...

I haven't had as much trouble getting spares as I did with my Xray. Things will get better.

There's been a lot of good advice here about how to build the diffs without burning them up. I'd start there if you like the feel of the front diff. You're running on carpet so the front diff may be the way to go.

If you want to run the spool, and it's rotating too much going in, try adding some rear camber. A little less up travel in the rear (higher droop gage number) may also help.

you can also try some anti-squat in the rear. You should get more on power steering and less off power steering. I like this option better than using droop as it seems to isolate front to rear weight transfer from left to right roll, which you want with rubbers on carpet. I have used this on a T2 and an Mi3 on low low low bite carpet. I responded since we were in the same boat with the Mi3 as it came with a spool and we had to wait for the diff. Even with the diff we like it as I said we have low traction carpet. Really smoothes the rear of the car down off power. your results may vary
