Seat setting

WILLIAM SILVA-CHERENA · Posted: Sun Jul 10, 2011 12:38 am Post subject: Seat setting

I'm moving foward the seat of an used shifter that I brought from a friend. The seat was off set to the right (right side distance was longer than left to a reference point at the frame). I think that I have read on a forum that this setting is normal.
But, which is better; the offset or a straight (same distance on both sides) setting. Question

I'm new to karting so please forget my minimal knoeledge.
Thanks

I'm pretty sure there is no "correct" position for the seat. Set it for your comfort “and” for good weight balance at the corners along with the correct balance front to rear. These numbers can change. If the kart pushes, maybe more front weight. If it's loose, maybe more rear weight. Moving the seat a 1/2", forward or backward, left and right, can make a big difference in handling, but you should be comfortable no matter where it ends up.

Tell us what chassis it is, usually there's a factory measurement for seat placement. The factory measurement is used as a starting point.

The seat is offset to the left to balance the weight of the engine usually 1" from center.

Sorry to bring this back from the dead,

I am having a hard time finding the standard seat setup for a GRG road rebel. I am mostly also interested in knowing where should the bottom of the seat be set? Should is be flush with the bottom of the frame or should it be a specific distance from the bottom for the chassis.

I know there are some jibs, but I was also reading this can be done with some wood or books under the chassis to support the seat.

I learned that we want 9" from the axle to the top of the seat on the rear, but not sure on anything else. Any help would be appreciated.

Please, at least use google. It's sooooo easy.

Tim how did you find that stuff? Maybe I need to work on the search feature a little more. But last night I only got about 2-3 hits.

You said you used google for those?

Thank you for the links.

Rear Edge of upper sear - 23cm
Front edge of seat to front frame rail - 58cm
Seat Bottom below frame - 2cm <- Is this saying that the bottom of the seat should stick 2cm past the lowest point of the frame of the kart?

So if you go over a kert, you are going to scrape you ass / seat bottom not the chassis. or am I reading that wrong?

"In time, your seat may look like swiss cheese..." <- haha I guess it always good to first get a cheap seat. Once things are working get a nicer/better one to drill only once of twice?

To find threads on ekarting, I use google.

Just type in the keywords you are looking for then put "ekartingnews" after it. Or, you can put " site:ekartingnews.com " before your keywords. Either way works well.

And seat height will depend greatly on your wieght. Heavier drivers usually will need a lower seat, to keep the CG low. Lighter drivers can raise the seat, to get more weight transfer in the corners. Also, low grip track needs a higher mounted seat than a high grip track.

Whenever you finally get to the track, go look at peoples seats. You will know who the fast guys are by seeing how many holes they have in their seat. It is not a 'set it and forget it' thing. It is THE biggest change to the handling you can make.

Yeah I wasn't thinking of seating when I was there on Wed. (I have been to the track a few times to look at different thing) but you make a good point.

So your expensive tillet or carbon fibre seat will have several holes regardless uh?
