R-kit has 4 super hard springs set (black), which is a special run from the original set Tamiya #42168. You also can run Tamiya BB-spring set (#42278/#42293) but then you need BB-spring retainers (14mm/#42192). Standard spring retainers in R-Kit are the 1mm up-type (#54776) which are only good for the old-type springs (13mm).
Therefore:
- Standard-R-Kit with the kit retainers: TRF spring set short (#42168)
- With new damper retainers (#42192): TRF BB spring set (#42278/42293) and all aftermarket BB-springs (SMJ/X-ray etc.)
Therefore:
- Standard-R-Kit with the kit retainers: TRF spring set short (#42168)
- With new damper retainers (#42192): TRF BB spring set (#42278/42293) and all aftermarket BB-springs (SMJ/X-ray etc.)

Can anyone running 48p gearing recommend a starting setup for spur & pinion for asphalt?
Medium to large size track. This is on 13.5 motor.

Chassis stiffeners
I'm just mounting the rear carbon fiber chassis stiffeners 280 a 07 with the carbon reinforced chassis all the holes do not line up perfectly I must pull the sides of the chassis 1 mm in words on each side to get the screw holes to line up is anyone else having this issue it is only in the rear not in the front thanks

you can see the center cross brace is too wide for the carbon chassis. I have to spread the chassis to get it in.
and the holes do not line up for the rear screws
If i remove the titanium screw from the rear and screw in both blue screws the titanium hole moves about half a mm. I have push the carbon in to get the screw hole to line up. this is on both sides.
I have none of these issues with the stock chassis.
Wondering if forcing these will cause some kind of chassis tweak?

I put the carbon stiffener on the stock chassis has same issue I wonder if it's possible the carbon stiffeners are made wrong or they are designed to have to be pushed a little to get it into the hole to make the rear chassis very rigid although I think this would add tweak

No problems with my graphite stiffeneres. Perfect matching holes.
Your chassis seems badly twisted. Would check tweak, loosening all screws and check step by step.
I had a similar problem with the Active Hobby stiffeners but the Tamiya ones should be perfect.

I think its the chassis itself not the stiffener. Seems you got a badly warped one. Before buying new parts, which I think it's not necessary, I would check tweak during assembly. Use a flat surface (glass table for example) and check if your chassis is tweaked after you installed all the stifferners. If its not the case you will be on the save side.

That does not need to be the case here.I have seen this before, one club member had the same problem with an brand new carbon reinforec chassis, i can be an production fault.
It will be better,when those braces are on,the stiffeners will correct the twist.

I doubt there's much weight reduction. Someone over in the FF-03 thread has been trying to shave grams for a while, and he bought a bunch of Tamiya CF upgrade parts only to discover they weighed the same as the stock plastic parts. He also tried to glue parts together instead of fixing them with screws, and discovered that the amount of epoxy needed to hold the parts together weighed about as much as the screws did. (titanium screws that is, not steel screws.)
Here's my report.
A Real Life Tinker Gnome: Weighty subjects. FF03 parts.
TL;DR:
Tamiya Stock plastic: 965.8g
After carbon plastic: 957.4g
Most of the weight savings was in the chassis tub. The bulkheads and such were hard plastic, and were usually slightly heavier than the stock plastic.
