It's infinity+infinitybillion times larger than stock (which is zero). :P
Any tank that would fit in the frunk (without cutting it up) would only be a few gallons.  It would also change the weight distribution of the car as fuel burned off.  The stock fuel tank is actually in a really good location as far as balance, and doesn't have any pickup issues at high Gs (at least until you get really really empty).

Big sway bars can make the car twitchier at the limit, and less compliant over curbs.  Generally speaking the bigger the rear sway bar the greater the need for LSD.  With an open diff, the big rear bar will pull up the inside rear tire and give us wheelspin.  This is why on my "stock" MK2 NA I run a 15/16" solid front sway bar and the stock rear bar.  I need that just to get the power down, even with the meager 5SFE.  This tends to create understeer in theory, but in part the stiff front bar reduces body roll which in turn reduces camber loss under load, improving my front contact patch.  Also, the rear tires are toed-out a bit to get it to rotate off the throttle.  Probably not a great idea for higher speeds at the track though.

In my experience the stock '87 MR2 sway bar setup is pretty balanced. I went to big bars (ST front, H&T rear which I think was 19mm) for a while and didn't like it, so I went back to the stock front bar and no rear bar.  There was an increase in body roll but the car was much easier to drive at the limit.

'Course, if we run stock springs, some stiffer sway bars are definitely in order to keep body roll in check.

We should add negative camber to the car as well, up front especially as the camber curve is terrible there.  Stock you can get just about -1.0 degrees which isn't enough.  -2.5 or so would be better.  The best way to "hide" this is with crash bolts - much less obvious than camber plates in the strut towers (but also less optimal).

Perhaps for our LeMons MR2 we could run the ST front bar and a stock 85-86 rear bar (or two?). 
If the fuel gauge works, that's probably good enough.  I can't recall for sure how long it took to go through a tank of fuel on my MK1 at the track but it was definitely long enough that a driver would welcome a break after a full fuel stint.  My trackday sessions were usually 20-30 minutes at a time, definitely not long enough to worry about fuel.

I think Bill likes this idea too much.

I imagine you can bet on anything in Vegas if you know the right people.

I didn't think those hats existed... now that I've seen them, I'm not so sure I want to wear one!  Too far?

Remember the mismatched junkyard tires on BMW bottlecap wheels that came on the black SC donor car? :)  It was funny. One tire was larger than the others!

Some pictures of the AW11 sideways:

It was so hard on tires though, I went through 2 sets of rears in one day even with only 145hp, and kindof gave up on the sport after that.  Too expensive.

And man, I sucked in those trackday videos.  I think you don't realize how much you've improved as a driver until you look back several years at where you used to be.
Hey Brad.  Congrats on your racing successes, it must be really rewarding to win a race as crew chief!  While you were at Long Beach I was a few miles away at the El Toro ProSolo.  Great racing weather in SoCal last weekend.

I've seen your Focus at autox events before, and could have sworn I had pictures of it. I can't find any right now though.

Ahhh, memories.  I sucked! :)

That's the Streets Of Willow racetrack at Willow Springs Raceway.  Not Buttonwillow Raceway.  And not to be confused with Thunderhill which is located in Willows, CA.  Oi...

Here's some crummy old Buttonwillow footage from the MR2 SC.  Seeing these videos again makes me realize what a jalopy it was at the time.  Steering off center, strange shift action...

Note this is Buttonwillow in the reverse direction.

How'd that one get in there?  ;)

I bet I could scrounge up some ashes around here somewhere.  ;)

We should totally put an F-Duct/RW80 on the car, even if it doesn't work. :)

I love it too.  Last I heard Toyota scrapped that design and are coming up with something new.  I think they'll be hard pressed to top (or even match) the car above.

And they say it will be light.

But that Sprite can actually use all its power. :)  Big slicks!
