I'd like to get closer to 40/60.

Can one move the engine back a few more inches? I know you'd have to cut the firewall and make a new drive shaft.

But for road racing the more weight I back (to 60%) the better.

Any ideas?

Are you serious?

It would be much easier to re-locate the fuel CELL.

Don't think about moving the engine, that's too much. It's already between the two axle centerlines, so it wouldn't give you THAT much.
Better off taking some weight out of the front and moving some of it back.

You could:
Relocate the battery
Install a lighter radiator
Remove front bumper
Install roll cage
Add a little ballast.....
PLAY WITH YOUR CORNERWEIGHTS!!!!!!

 

That sort of change is going to be tough without reworking the chassis. And I'm not sure 40/60 would be all that ideal given the power level.

Delrin or solid aluminum motor/tranny/diff mounts would be lower profile, allowing lower mounting of each. More solid response too.

Dry sump motor for increased ground clearance.

Hack off a-pillar, remove windshield and soft top. Replace with small wind deflector for driver and tonneau cover for cockpit.

Generally you want to try to move the weight lower and towards the center of the car, as opposed to one extreme end or the other. Putting your battery down where the passenger's butt would go might be useful.

And you know with that wing, the load distribution on the tires at 95mph is probably about 40/60 f/r?

 

I don't expect to beable to get to 40/60 nor am I doing this anytime soon. Just wanted to open it up for discussion.

jzr: good point about the wing.

 

Why is 40/60 better than 50/50? Rear tires will have more grip? Harder to upset rear?

 

In simplest:

When you brake you move weight forward, when you accell you move weight back. More Weight (from static) moves forward than back because you can usually can brake a lot harder than you can accelerate.

So w/ 60/40 you have near 50/50 under braking and more weight over ther rear tires under acceration which yes, creates more rear grip. And a better ballanced car on the track.

Btw as jzr pointed out 60/40 might not be the right combo for the s2k but is a number that is the goal for many rwd race cars.

 

Do you still use the OEM fuel tank? What about cutting out the bottom of the trunk and putting a racing fuel cell in behind the rear axles?

I read your post, but Krazik didn't respond...

 

I don't respond to slick rick.. he's trouble.

BTW: you can't really move much weight w/ the cornerweights alone.
