Hyper TT tuning session 42 (of infinity)

I spent the afternoon at the track alternating between testing springs and oils in the Hyper TT and building my 22T 3.0 when they were watering.

Current setup on the Hyper TT is:

Ride height:  
27mm front/rear

Front shocks: 
kit silver springs, 37.5wt TLR oil

Rear shocks:
Losi 2.5" blue springs, 32.5wt TLR oil

It'd be nice if someone made a stiffer rear spring than the Losi blue, but I haven't found one yet.  The firmer oils helped, and I may go even stiffer, especially in the front.  The truck is very composed now.

Diff fluid:
Front: 10k
Center: 40k
Rear: 5k

The 40k center diff oil is a big improvement over the 7k I was using, but I definitely had to up the front/rear oils to 10k/5k.  I'm also running a little more toe out, probably 1-2 degrees.  It helps, and with the thicker diff oils it still drives fairly consistently down the straightaway.

The springs I've found so far that fit that are a decent rate:

(from soft -> hard)

Front springs:

• Losi 2" black
• Kit silver
• Ofna Hyper 10SC white (hard)

 Rear springs:

• Kit silver
• Ofna Hyper 10SC white (hard)
• Losi 2.5" blue
