As the R uses regular TT02 top and bottom arms I believe you can shorten to 251 like a regular TT02. The alloy hubs shouldn't stop you doing that. Caveat: I don't have an R but too many normal ones and far too many Type S versions lol.

I've also got the fancy hard chassis.

I too have the Hard Deck in blue on my recently rebuilt Type S. I ran it last weekend on gray carpet with an old 17x2 brushed motor and it felt very direct. I like it a lot.

If I bought a TT02R, what are other must have upgrades for TCS?

Hello All,
After 7 years I am getting back into an "on-road" car after my F201 and TA-03 were stolen in a home robbery. I found a sealed TT02 Porsche RSR on RCgroups for $100 delivered so I thought what the heck. I am a big rally fan (I own a full scale '84 Audi Turbo quattro coupe) and plan on building this into a rally car.
With that said I have read quite a bit on the TT02 last night but have some questions on some parts I am looking at.
Shocks- Are the 54753 Super Mini CVA the correct shock to go with? As for oil should I go 40wt or drop down to 30wt for rally?
Shims- One thing I have learned about Tamiya kits over the years is that shimming the suspension helps a lot. I am assuming that I need 3MM ID shims for that? I have also read that it is a good idea to shim the diff's and wondering what size shims I need for that.
Steering- One thing that annoys me is sloppy steering. While I am trying to keep this a pretty budget build and not looking to go full Aluminum I am wondering if the 54550 stepped screws are worthwhile? They are cheap and I have read some positive reviews. On the TA03 it was common practice to use small o-rings in the ball links to take out some slop, it this necessary on the TT02?
Differentials- So I am use to ball diffs but reading about using different weight grease and oil in the diffs to get the proper limiting effects. I laymans terms what should I put in the front and rear?
Bearings- Already ordered.
I also have an old Novak Havoc 17.5 turn motor/ESC which was going to go in the TA03 back in the day. The motor looks like it is 2200KV so I am guessing the stock gearing would be fine?
Anything I am missing?
Thanks.
Cheers,
Jim

My M05, and TT02b both have.. pretty sloppy steering. Well "had" sloppy steering. The M05 I swapped out for metal steering gear. I have it ordered for the TT02 as well.
To reduce slop on any ball cup, I use a slice of silicone tube that's ~very lightly lubed~ with light oil. The slice allows adjustment of the preload on the ball cup.
IIRC, the shims for the differential are 8mm shims. (at least that's what I ordered for my car...)

Thanks for intel.
I did a bunch of reading on diffs last night and I may be more confused now then I was. The car will be used on unprepared tarmac and dirt. It sounds like the less grip there is the "locking" you need? Anyone care to take a educated guess what I should run. I will not be racing at all but just looking for some guidance here.
Thanks.
Cheers,

We've started a spec class at our indoor racing club - TT02, Torque Tuned motors. Basically kit plus bearings. No other mods.
Some great racing is happening, but last night in one race 3 of us all lot a front doggone in one race. I understand the flex and slop in these things, but is there any cheap way of minimising this? O rings in the cups or anything? Or just accept its going to happen from time to time?

Aah ok...
My friends and I are driving the same rules as your class states, but later allowed this "tuning" as it doesn't change your speed and gives the freedom of contact racing. I for myself never had a problem with bones falling out. I guess it is a little different with each car...
