What split are your tires?


Try This:

droop= front 1 rear 4
camber= front 2 rear 4
toe in = 3
toe out=1 each side
2nd to lowest hole for rear shock position
24tooth side pulley 2 1/2 split on tires


Let me know how it works out

also try 50k in the rear diff and toss your rear roll center bushing into the highest postion my 4r is planted off throtle it never even thinks about comin around but its loose enough to really corner good and go back to the blue springs

I would say that if you really want to change it and can afford it, the capricorn clutch would be the go if they make a set for the Mtx4r

great motor when u run it in get it goin a little rich and run it like u stole it get the temp to 200 or so shut it down let it cool off and repeat for about 4 tanks of fuel and you'll be good to start tuning for race when u start to lean it out make very small movements, factory settings r very close to a good tune. these motors dont need a long break in process like other motors ive ran a gallon through mine and it keeps getting better, i love it ive got the temp up to over 300f on accident with no ill effects the motor still looks new inside if u need any advice about it send me a pm


and have fun youll love the mugen its a great car i get my first chance to run the capricorn on sat its got big shoes to fill as far as im concerned

Default rear shock tower

I have a quiestion:
today during my main the rear shock tower go off the car, don't broke just go off,is the second time that happens to me, I am using 4mm rear shock tower, i change the plastic that hold the shock tower(covers the rear diff) and it happens again today any idea? I am using the screws that the 4mm shok tower have in the pack.the last time that happens and today the track conditions were bad and i was using stratus body, usualy in good conditions i ran with altis 2.3 or audi but when is cloudy or the traction is bad i ran with stratus, can it be the body???...

I know is wierd, I am running 4 since 2005 and i change to 4R on 2007 and change the kit for anew one on 2009 and allways use the 4mm rear shock tower with the 3x10 stock screws that comes un the pack of the shock tower, I'll move to the 3x12 or 3x14 with thred lock
