My T4 setup..

[sticky]

I'm running mine on proline gladiator tyres on the rear (for grass) and schumacher staggered rib on the front. RPM wishbones all around with the RPM ball ends and lunsford titanium turnbuckles. SRT caster and steering blocks on the front (when they arrive from USA.) CVD driveshafts and a one off steel hinge pin holder at the front of the rear. Electrics are a 5000 mah 60C lipo through a 60A ezrun with a 5.5 T brushless motor, the best Futaba servo, standard spur and 26 tooth pinion. 35wt oil all round, wishbones below level when truck is settled.
Goes so quick you need to cut out the back window to let the air through and stop wheelies!!!! Also use an old B4 shell velcro'd onto the chassis (under the truck one) in bad weather / conditions as it reduces the water muck risk to your electrics hugely (with blu-tak added over the spare receiver holes, and electrics sprayed with inox mx3). I take it to the park and let my 4 and 7 year old kids play with it (they steer, I control the throttle!). Nothing bust after 6 months......
Goes quicker than just about anything else this scale! Eats nitro cars and trucks for fun ;-)
Enjoy it stock or tune it up, they are brilliant trucks and always make me smile :-)
Cheers.
