When you install the pulley on the front diff. Make sure you are just using the one side and not attaching the plastic belt guide for the other side... That is only to be used for the one way or spool... this should solve your problem with the fitment..

Im sure i placed the dif and bearings correct!!! So lil-bump what i have to do?? I cant place the front bamper stay when i the dif is all way down! the space between the bulkhead is more larger!

staikosn1,

Let me ask you this: When you built your front diff and put the front pulley onto the diff, did you use the separate ring (part #T0258B) as how you do on a Front one-way?

If your answer to my question is YES, then that is your problem. Take that ring off and it should make the front diff fit right between your your bulkheads.

You SHOULD NOT use that ring on a front Diff. That is why it is separate from the actual front pulley.

Good luck!

You are corect Ron C. I didnt even thought about that... Damn.... Thank you Ron C!!!

actually, tire wear front vs. rear is something about the overdrive too. So for ex. when you use 24t pully with 1mm split, fronts will wear more than using 2mm split, because its dragging. and you also feel more comfortable with some overdrive at front. so, if you want your front tires to wear more equal to rears;
you can use less split,
use solid at front,
some softer tires at front, or harder at rear. maybe f37 r42. i havent tried this but makes sence since the car has understeer.

I prefer driving a car with rear tire is rotating faster than front ( kind of 2wd ). I accomplised that by using 24T front side pulley and 20T rear center pulley ( pulled from MRX4 ). I use 40 shore rear and 37 front to minimise the chance of rear tire getting smaller than front's after 30 or 45 minutes final. This is also help to reduce understeering in my car.

In the past, I get sucks driving feeling after 20 minutes driving. I notice the problem when rear tires have same diameter as front's, eventhough I already start with 4mm split.

This does make alot of sense about the tire compound. But looks like i got conned at a LHS a few days ago. I was adament about getting 37f and 40r.. But the guy insisted it was the other way around. So I thought he knew better since im quite a newbie to this, but it just made basic sense to me, I may have not been with RC's long, but im a huge motorsport fan..

I think I maye just leave on the 40f and get a 42r to match it, and keep the 37r and get another 35f for spares.. I'll practice with the harder ones first..

Thanks all!

Hi..

Dont get fixated on this... different people run different tyres depending on many factors.

Run what you have and see what you think... If you are are inexperienced you probably wont be able to tell much difference and those tyres wont last very long at all anyway... about an hour of running is as much as you can expect.

I would say this however ...

I am sure that you, like most others, will eventually want to run the 24t front pulley.. the most effective way to do this is with a 2.5mm offset.

Save up for a tyre truer, Integy do a manual one which I believe is really cheap in the US (Under $100) It will be one of your best purchases if you get serious.

I use the Ceramic Nitride Pro Series on all of my car kits, they are the best on the market. If your not sure about the kit don't think twice, just get them and you want be disappointed!!!

Good point .. maybe it was a marketing thing for when the car was first released or maybe it comes with R decals or something?
