Ground clearance.

OK so with things so slow I figure it's time to get some input on ground clearance. So you low slingers out there, what are you running? I've seen some that look like maybe 2 inches, and some with 4-6. I know a lot of it depends on the terrain, and whether you need to clear praying mantis' and such but what seems to be the average for the low slung competitive Karts? Thanks in advance and have a Happy New Year.

I've got 4", which seems to work well in mixed dirt/pavement use.

Dave is right on at 4" being close to the norm.
Your 17" wheel with tire will set your front spindle at 11"
Using the formula: Ground clearance = 4"
Belly pan below frame = 4"
Frame rail = 3"
Total = 11" which puts your spindle centre at the same level as the top of you Frame Rail.
With the Rear Axle passing though the frame gives you a slight rake by raising the rear 1" to 1 1/2"
Hope this gives you a visual with numbers.
Good Road
Brian
PS
I would not go lower than 3" of Ground clearance if you want to run in the Campbell Cup.....Orchard is rough!

Thanks for the responses. I was figuring 3 maybe 4, but wanted to know what actually worked rather than go all in and be disappointed. I've found a 27 inch double eye spring at 1000 pound rate, but it's three leaf so stripping it to one and cutting it in half should get the front on track. I keep going back and forth on a plywood laminate frame and the tried and true metal. I think the wood is a better learning tool for me and very interesting. I've been studying the Jappic build online, and how the Supermarine Spitfire wood joining was accomplished and it just has a feel good side to it. I'm not going to be beating the thing to death, but want to learn on this on, then reach a little higher on the next one.

Hi Justin
Your new Ck is looking quite wonderful.
What is your wheel base? And how did you clock your TAV?

Thanks!
I posted on that thread with a pic that kinda shows it (only one I have on my computer at work). The wheelbase is 65," tav is clocked at about the 4 o'clock position.

I'm running about 4.5"

The only thing that has high centered me was a tall curb I rolled off slowly.

and in the corners, it feels rock solid
