Yes that is worth a try. I also understand that a softer rear helps keep both rear wheels on the deck for grip in the corners. So this will be a bit of a balancing act...

Re: Firebug's TF track car gallery thread...
I believe an answer to the wheel spin/slipping gearbox question has been found?
Just like ASSHAT only ... BIGGER!

Re: Firebug's TF track car gallery thread...
Yeah my modified dipstick tube was playing tricks on me. Seems i hed nowhere near enough ATF in the gearbox, resulting in its demise. I have it sussed now though i hope. I'll post a bit more detail one I'm back home.

Re: Firebug's TF track car gallery thread...
So Dave and I entered a Ringwood event in March this year. No indications of any mechanical problems in my shed in the week prior, or loading on/off the trailer. Scrutineering saw no issues and away we went. However there was clearly something amiss on first lap of the day. No 2nd gear what soever, just a free spinning engine after 1st ran out of legs. On some areas of the track I managed to get 3rd gear, but only due to some distance between corners. Back to the pits to check oil level. Oil looked low so gave it a splash back to full. Checked for leaks, no leaks, still no 2nd. Checked some logging with Sam around lunchtime over the phone to see if the selectors were the culprit, but the logs were s%*tty and offered him no solution. So f*#k it, I raced the rest of the day with no 2nd gear and picked up Third Place In Class... lol
A couple of weeks later I chucked it up onto some stands and spent most of the day with DaveHAT swapping out said transmission with one he kindly loaned me. Thanx again Dave!
We dropped the fluid out of the box. OMG the smell was awful, as was the colour. Brown, burnt, and full of metal shavings and pieces of band. "There's ya problem right there..."
Ewww...
Biggest piece of band
And stay out!
Replacement box went back in, bolted up, dinner was ready, shed door down...
Convinced I was cooking the oil to such a state, I picked up a second cooler and mounted it up front on the passenger side just the same as the first one.
Original setup:
Trans oil cooling 2.0...
So last week I finally got around to tidying up the Gem and refilling the transmission with some new oil. The flexible oil filler/dipstick tube I made was giving me a false reading on the dipstick. Long story short there was a a join at the bottom of the tube that held a seam of oil when you poured oil over it when topping up. This seam slowly dissipated down into the sump over a few minutes. However if you check the level before this happens, as you remove the dipstick the seam of oil deposits a little onto the face of the dipstick a couple of millimeters above the full mark to the bottom, giving the impression it is full.
Knowing it was nowhere near full I checked the level anyway, and there it was on the full mark... WTF? Scratching my head for a few minutes then checking again saw no oil on the stick. So back and forth I went adding a bit more, checking, waiting, checking, adding, etc, eventually getting a reading on the stick that made sense as I added. I took a few pics of the results with my phone but it was too hard to see the oil on the stick.
So it seems I've been racing with minimal fluid in the trans. It's a wonder it lasted as long as it did. Looks like I'll have to order a new flexible dipstick tube from Summit to eliminate any future oil level related issues...

Re: Firebug's TF track car gallery thread...
I would suggest the breather tube should stop this from happening, but that said the flexible dipstick will be way better for your tight setup anyways and probably more accurate than that tube one we made
i always thought your car "slipped" out of corners like it was low on oil then got some and off it went, but like you the dipstick always said it wasn't and i figured it was just actually wheel spinning a bit due to copious amounts of horsepower!

No matter what the question is, the answer is always more horsepower!!

There was plenty of mind trickery going on Sam. Not a hard feat in my case...

cross check all the settings and see ?
copy all the data from the old one to the new one ?

Might have to call in one evening with phones and reference...

Re: Firebug's TF track car gallery thread...
Let's see if a gearbox with almost 300000km is the answer to going fast!
Positive result from this ... we now have a "bank" of transmissions at our disposal should the need arise.
Hopefully the new fuel pump & relay in mine and "race" transmission in the Gem will result in many trophies ... and by trophies I mean stories of what was almost & could have been.
