only suited to non tech tracks like more flowing arangments but 7-5-5 doesnt seem to suit anything

Hey Guys,

Managed to go down to Southern Alley track (Johor, Malaysia) yesterday (my first try on proper track) and I seems to have problem with cornering, when I turn and full throttle the back seems to skid left and right.

i believe it might be the BUKU clutch that I'm using, might not set them properly thus causing that. Maybe i'm being too ambitious to go with BUKU, should dial my driving first before considering BUKU. (Disclaimer, nothing to do with BUKU, just me not doing it correctly)

Next run I will try to use the stock clutch to see if it solve the problem and try to improve my driving (like what someone told me, learn how to walk before you start running ). But overall it's a tough buggy! had a few bad (some real bad) jump and even managed to go out of the track and into the drainage but it is still going strong!

On a separate note, do you guys maintain 2 buggies? One for practice and one racing or you guys just maintain 1? Using them for both practicing and racing. I was advise to maintain one as I was told no 2 buggies are similar even how similar the setup is. You tend to suffer if you are used to the practice buggy and on race day, you are using the racing buggy which you often don't drive. Your opinion on this?

i see time and time again people put option or hop up parts on their cars before getting to grips with the car at stock and wonder why the car is a pig to handle try find a base setup and start from there before adding parts etc, so you know whats going on with the car.

Default weights

I apologize if this has been gone over before, I've tried to search this thread but it's h u g e! What are average weights for the MP9 with/without upgrades? Are there limits to how light it can be and still pass tech? I guess it varies between racing sanctions. Just trying to get more info on weight and corner-balance. Thanks!

By that, I mean even when just slowing by engine braking/backing off the throttle, the back-end would always want to come around and the car would oversteer even with just a little bit of steering input.

Not sure how you came to the conclusion it might be too much front brakes for you, as normally too much front brake would cause the car to plow straight on, understeering heaps. Too much rear brake would cause a car to oversteer.

Anyway, for me, it turned out to be because of the ride height. I started out with Cody's general baseline setup and the way he sets up his ride, with 1-2mm lower front ride height than rear, just made my car have WAY too much off throttle steering. I setup the car so that front and rear ride heights are the same and problem solved.

A quick and easy way for you to figure out if the problem is being caused by too much front or rear brakes would be to simply unscrew the rear brake rod by quite a bit, so that the car has only front brakes. Then see if the problem is still there. Do the opposite, so fronts are effectively disabled and you only have rear brakes and you'll know exactly what's causing the oversteer issue, whether it's too much front or rear brakes.

If the oversteer still happens even when not using the brakes, perhaps like me, it could be a setup thing. Give that a try and see if it helps. At the very least, you'll know for future reference, what too much front or rear brakes feels like.
Hi guys,
where do you measure the front ride height? I usually measure it where the downstop screws touch the chassis. Is it correct?
