Lets talk gearboxes

I'd probably put a Quaife ATB in, they drive nice without being intrusive on the street and would be a huge improvement on the current open-wheeler-peeler, even if not a total winner for the last tenth on the track.

Yeah, that's what I was thinking, and it's half the price from my loose research. I was comfortable at that price point, no so much at $4k considering the value of the car. 1-1.5sec would be a nice gain, but I'm only out there for a laugh rather than a lap time.

Just that the feedback is suggesting it's worth the extra coin.

Hoyhoy.

I'll put my two bob's worth in here.
Some of you will know that I chucked my low km but used torque-bias diff in the bin, never to be seen again.
When coming hard out of tight corners on the track it made the inside (lighter weighted wheel) to spin & grab & spin in a savage way.
My thoughts are that it only put a lot of extra stress on the gearbox.
I found that the plated diff has made things a lot easier to get better times, then ya can look at other things to get the extra tenths.
Now there are some side effects of the plated diff, being some clucking, just like a rear wheel drive plated diff.
But ya have realise that the Little Blue Girl only gets driven twice a year to Wakefield Park to track & back.
The funny is that she doesn't have any clucking after the track day, which could be from the Red Line Shockproof Gear Oil, I have read somewhere that this oil puts a coating on the gears, so I don't worry too much about the noise, it sounds masculine in a way, just like super performers.

Why not a WaveTrac? That's my current leaning as it is mainly a TBD but does have some locking if it differentiates too much.

Peter Jones ran a Peloquin in his old MkI and then changed to a WaveTrac (before building the Kamei and transferring the WaveTrac into that) and said it was noticably better. One wet/dry track day, he said that he felt he would have spun it a couple of times with the Peloquin but the WaveTrac steadied the car - I imagine this was in those situations mentioned by Eddy where his Peolquin made the inside wheel spin/grab/spin in a snatchy way.

I should have got one when our dollar was much stronger
