the side front pulley is 25T.
i tried run the 40 Front (4-5mm) and a paired with set of new rear 40s.
This way i thought i could get more grip but it didnt.
Instead, the front was heavy than b4 and causing the car to run wide if i get on the gas entering the corner. So this understeer problem still exist not until i put on the new front tyres.
any solution to my problem?

Forget all this pulley talk.

Simple solution is to keep the front and rear tire diameters the same or very close. Handling will improve as the foams wear down, as long as you keep them the same front and rear.

when the engine idle and car at stationary, i noticed the clutch bell was spinning slowly making the spur gears to spin as well. Is this normal? But the car is standstill.
i started noticeing this after i hit the board at the cap screw area on the crankshaft without the body on and the engine died after that.
But i did dismantle and had a check on the bearings & parts...all seem in working order except the clutch bell spinning slowly when the car is at standstill.

Anything wrong here?
thanks

Nope this is normal. You will notice you can spin the 2 speed unit backwards without the car moving. It is just the engines vibrations making this occur.

RClover

phew...!!! thanks for ur info.
BTW, what is the chance of getting the crankshaft bend (front portion) ? are these shaft super duper strong and made to last?

Also, what would be the most significant difference (in terms of driving feel) if i change to a solid rear axle from a diff wif 100k grease?

how long did the 40s Front & Rear tyres lasted on your track?
also, what would be the most significant change in car handling if change to a rear solid axle from a rear diff wif 100k grease?
thanks million...

great on power steering and straight line stability

where the heck did you get one for us 250!!???

RClover

juz saw a K-factory solid rear, is that good?
And how long did the 40s Front & Rear tyres lasted on your track?

I have this solid axle on my V1RR and it is the lightest one available. I also have the kawahara one.

my solid axle is on the way. hope i will like the handling and find a good setup for my 1st ever race after lunar new year. There is a new track near where i live, approx 38km away. A permanent parking lot converted track about 120ft x 35ft.
I tested out there yesterday and found the track is to be medium-high traction. Overall the handling is much predictable now than another temporary parking lot track that i used to play. Tyre wear now is much reasonable and i will try out 40/ 42 shores.

But one thing i noticed though is that the car seemed drifting quite a bit when i powered through the corner. Drifting effect means more tyre wear? the car run wide if i powered too hard through the corner... How should i correct this?

Thanks Manti and guys...
