310 (6 speed) vs 360 (5 speed) - thoughts?

[chemistry]

Having almost pulled the trigger on a 360R with a 5 speed and LSD, for a 90% road, 10% track toy, I'm now wondering whether a 310 with a 6 speed box might be more fun.

I realise the 310's Sigma unit isn't as upgradable as the 360's Duratec, but I've mainly been agonising over the gearboxes & final drive ratios. I know that most folks recommend a 5 speed in the 360 for my sort of use, but it just seems...well, so old fashioned. Head says 5 speed, heart says 6 speed "because race car".

So, might a 310 with a 6 speed be the sweet spot?

Thoughts?

Thanks for all the input...back to my brochures, spreadsheets, etc.! Actually no, what as I saying? This has gotta be a HEART purchase; that 420R idea suddenly sounds an appealing third way ;-)

All advice gratefully received, please keep it coming...

1st and 2nd are both higher on the mazda box so it's definitely better than the t9. Still too wide ratios to be ideal, but the 6 speed ratios are too close to be sensible, so there isn't an ideal solution.

This, sadly, is exactly the problem :-(
