Whatever you want it to be, I use 61.5mm everywhere I go.

60-62 is the general range. Just make sure your shock length isn't limiting your droop, which can change as you make adjustments, especially lower arm mount heights (roll center).

The method I use for shock length is:
Assemble the shock, do not put oil into the shock body.
Press the shaft in, while resting only the bladder on the top.
When the shaft moves thru the body, the piston should not touch the bladder or move it off the top of the body.

Put the cap on, measure the lenght and match both right and left side.

Doing this will ensure that your shock will not press against on the bladder causing oil to leak as the bottom side of the shock will prevent this.

This will also ensure that you are using all of the available dampening.
Once you find the proper length, write it down in the manual so you don't forget.

I'm sorry, I want to clarify,

I'm going to buy some after-market shocks. They offer it in three sizes:

50mm, 55mm, 60mm

I'm a very newbish for touring cars so was wondering what sort of length are usually found on touring cars such as TC5s and TA-05s.

I'm going to be running it on indoor carpet...

I heard that for super smooth tracks, 50mm, for "rougher" tracks, 60mm.

So I guess 55mm for best of both worlds?

I don't know what "smooth" and "rougher" tracks for on-road are, I come from off-road, all on-road tracks seems smooth to me...

Shocks sold in sizes like that are junk.

Just buy the correct option shocks for your car.

i have to disagree here ,

i bought some cheapo shocks for my M03 and they are better then the better ones you can get for the car

they haven't leaked a drop of oil and i havn't tooched it for 8 months

my TRF dampers on my 416 need new seals every 2 months !!!

You must be running in some shocking conditions, or you must be doing something wrong.

I've run a couple of cars with TRF dampers in the past, racing most weeks, combination of indoors and outdoors, damp and dry, never had a TRF shock leak, never changed a seal, never had any sense of the shock being less than super-smooth. Built exactly as Tamiya suggest.

Each to their own I suppose.

I ran a set of TRF shocks for almost a year on carpet, the dampening never changed, no leaks, absolutely perfect. I opened them up, oil was crystal clear.

For reference: 61.5mm, no bushing, 3-hole piston, 20% rebound and TRF springs.

It depends on the car really. For example TRF shocks won't work on a Pro4 out of the box. The shorter ballcup is too short and limits droop, the longer ballcup is too long and makes ride height too high.

I've been running my fluorine coated TRFs for 5 years now on everything original and they still don't weap past the seals and hold their rebound very consistently.... best shocks ever created and the mi4 ones are basically a carbon copy of the trf shocks.

Other companies have a lot of catching up to do in the shock department.
