Update: just got the kit in the mail today!

So I've measured the 70 tooth spur (48P) included in the kit and its 43mm in diameter - how does that compare to the diameter of the 105T 64P spur?

I'm hoping that the finer pitch combined with the lower number of teeth on the 95T spur will fit.

If anyone has a 95T spur could they post the diameter of the gear?
Hmm, I dont know , to me it sounds like it must be as per original kit - meaning no changes - best you find out what they mean exactly

By the way the 70T spur is not 48P...it is of the .6 variety.... with larger spurs - 95T , 105T - being .4 kind ( some say that you can use the metric with imperial pitch but I havent tried it)

@snewman
Been running 48T motor that requires a low final drive ratio setup and i can safely say, yes you can fit in a 95T pinion.

Currently, i'm using a 64pitch 43T pinion and 90T spur.

I read over the detailed rules and they're okay with hop-ups as long as they're standard off the shelf items made for that chassis.

Good point on the gear pitch - I forgot that the Tamiya's use the metric pitch. I'm looking to change over to 64P anyway as there's a broader range of spur and pinions available.

Thanks for that - I'll go ahead and order the spur and pinion.

What have you guys been using to glue the diff plates to the outdrives?

The manual talks about "synthetic rubber cement" while I've also seen others using CA (eg the build project at side-fx - sorry can't post URLs yet).
I ended up using Tarzan's Grip very sparingly, cleaned up any excess and polished the diff plate. Worked great.

very minimal would be the difference. your internal ratio would go from 2.05 (with the 37T pulley) to 2.00 (36T wide pitch pulley)

not sure if you would notice a "performance" difference.

Noob question time?

The setup sheet has damper retainer normal or 1mm down.
Can someone please explain what this is?

Cheers

the stock (plastic) spring retainer (depending on other factors within your car like shock length, stock shock tower or hopup, etc) sometimes prevents you from making ride height.... so Tamiya released the hop-up spring retainer that lets your spring sit 1mm lower so you can make ride height.

so if you find you've loosened your shock collars all the way to the top, and still cant lower your ride height, try the 1mm spring retainers to help.

Default Spoll problem

Appreciate all your help guys.

Problem:
Try to install Tamiya spoll, had to bail out of GT3 last weekend at TCS

This is what happened:
When my wheels are pointing either left or right - throttle anywhere from 20% to 100%, there is a significant amount of vibration, it sounds even worse "KRAK KRAK" but not a full lock.

If the car is on the track it's like the front dog-bones are out of place. the front of the car jumps up and down.

The problem is not there so when the wheels are pointing straight. The problem is also not there with stock front differential installed.

Any thoughts?

Thanks!
Marcos

the chatter from the spool is probably causing havok with the dog bones. if you can upgrade to universals, your problem might be solved....

thats just my guess. you could have come up to me. i was running a TB-03 in GT3 at TCS last weekend.

oh.. one more thing.. you use steel swing shafts (pictured above in 44mm) and alum in the rear for the TB-03.

46mm for TA05V2.. but varies depending on your suspension blocks
