You'll probably get as many opinions as there are chassis.
Do a search on...
Raw Striker
RoadRunnerRacing SR2
MK Indy
MNR Vortex
Mac #1
Westfield
Sylva Riot
...and thats just for a start.

I suggest you look for the lightest chassis when all built up, put a passenger into a BEC and it will slow down, do not start off heavy.
So if going for a home brew then Ron's over Haynes, its's smaller and lighter.
As it's for track look to land a full cage where tubes align so build the cage into the structure rather than place on top and use the correct
tube as specified in the MSA blue book.
Regards Mark

Not the tiger unless your off for a small engine.
My zzr1100 won't fit without 50mm out of top and 40mm under chassis.
Zx9r wouldn't fit without cut out either.
My old locost chassis worked well with zx9r and zzr1100
Thanks

Building my tiger avon slowly but surely.

Hi
Track use only moves the goalposts somewhat, so here's my 2p:-
Sylva Riot or something similar - i.e. rear mid engined..
Engines in the right orientation, simple install, no prop etc and hence it'll be very light..

A bike chassis would be ideal

+1 vote here too. Great chassis and fits a bike engine well. The only issue you may have is the height of your chosen engine as the Aries/ST is quite
low compared to others.

For track days only I'd go for a Procomp chassis. See www.procomp.co.uk
To be honest, you'll have to ask them nicely to do the bike mounts for you but they are good guys! Being Live axle the only engine that you can
really use will be an R1 1998-to-2008. Plenty of choice.

+1 for the lightest you can find and build.
If your out and out track then it needs to be small and light. The smallest cars I know of are
RTR (road track race) Atomic
Sylva R10T
RAW Striker.
RTR Atomic is single seater but with the engine next to the driver for optimum COG. These cars are tiny!
Track days ARE the best thing since sliced bread, until I get a supercharger that is!

I suspect he means because the inj' R1's have a higher final drive ratio than other bike engines, so work better with the available live
axle diff ratios ???

Exactamundo Adi. Carb'd 'Blade is the other option but why would you these days?

Easy emmisions, good power to weight and stick in a baffle plate and you are on the track so very cheap with a plentiful supply of replacements at
under £400.
A good 893-919 blade car well driven will beat others and gears are perfect for fixed axle/cheap sierra ratio's, so cheap to start off with and
cheap to keep going.
