Usually it is best that you choose as your start set-up the one that you use at your home track. Then you have a comparison with what you are always used to. Which engine and tires are you running? If you know where a better one is, post it below. If you have too loose of a setup though, you wont be able to have the kart plant itself in the turn and then you're coming onto the throttle either too early because you're sliding through the turn , or too late because you've slid into the turn farther than you thought. . Idk about that last piece though.
Increasing toe out will increase initial cornering response. Always think of the kart as a whole and that you need to have a balance. Good luck and have a safe day racing. I then measure from back of seat to axle, this measurement depends on your axle thickness, for a 50mm axle I use 180mm. This would usually mean that an axle change to a softer axle is necessary. I have 1mm toe out each side, about 2degree positive camber.
So that's been guiding the setup so far. Camber is adjusted by rotating the camber adjusters at the stub axle mounting. Raising the chassis height creates more leverage in which to transfer side weight to the opposing tire and thus results in more front end bite at the entrance of the corner. Stiffness has to be removed from one or the other. Widening the front track will create more flex in the front end of the kart and result in more front end grip and quicker turn in. I know you want chassis setup, but that could change depending on certain engine or tire factors.
Do you have a picture of the back of the kart? By moving both spindle spacers to the top of the spindle, you are raising the front end of the chassis. Hes able to be smooth since hes not upsetting the balance of the kart. Not sure about any other companies Yeah the overlap in designs seems to be a hot topic. You can now slide seat back and forward at desired height. Birel Kart Setup Birel karts. A perfect setup should feel like the kart floats through the turn, no upset of the balance from turn in all the way through to track out. That way, when they're 1 session old, the kart is setup for the most amount of grip possible from the current wear on the tires and would be perfect for the track.
I want to experiment with more chassis changes this off season, so I'm interested in suggestions in how to do so. By rearranging the two spindle spacers, the spindle height of each side of the kart may be changed. Especially with so few actual manufacturers of chassis. Look to other adjustments first to correct handling problems before changing your toe settings. Tire Pressures : Starting at 9 - 11 lbs.
It's a good mix, medium speed corners, not much high speed cornering, and few low speed corners. Most handling problems that occur during the entrance of the corner are probably results of improper front end adjustment. Nitrogen gas is recommended to reduce air pressure variances. Toe-in settings: 0 deg - on kart stand begin set-up Camber : can use offset bushing depending on front tire wear - 0. The excentrics are small in size but most effective on the track performance.
Please note, if you have a kart that is pushing badly and you have already done all things to put more grip up front, then you need to take grip away from the rear. Basically this means if the seat isn't in the right position anything else you do is a waste of time. As a general rule, the grippier the track or tyres you use, you would move towards 200mm. Keep both sides the same height. It depends how you drive the kart and what class you're racing in.
However, it should also be noted that Sarno is a track with smooth turns, not necessarily tight angular turns that require a lot of turn-in. More weight forward - gives more front grip. Just speculation based on testing. The front ride height is neutral 50% available spacers above and below the spindle. It does this by transferring weight to the opposite rear wheel during cornering. Anyway, its worth a watch. The lower the kart is at the front the more direct the chassis will be, while losing, however, on efficiency after the angular point.
