Hello!
I'm trying to find somewhere in Kent (preferably Medway) who can lighten and balance an OEM flywheel for a 1.8 MX-5. Can anyone suggest or recommend an engineer or machine shop who could do the work?
I've spoken to iamotorsport, who would have been able to do it before they sold their lathe!
Any suggestions welcome, many thanks,
Neil

Kent is a big place, but have you tried baldyne's at biggin hill? baldyneengineering.co.uk/they've done some stuff for me in the past and it was top notch |

Thanks for the lead - unfortunately baldyne are a bit too far away to be practical. I'm based out of Ashford, and the guy working on my car is in Chatham.
I'll mention it if we get stuck - something might be possible.
Any more suggestions?
Cheers,
N

Hmm, yes the alternative is to buy something - but that will prove too costly for me to justify (I'm considering a lightened flywheel while having a fresher gearbox installed). Plus that flywheel's lighter than I want - the car will be mostly for road use, and I just wanted a little more pep... |

i have one in a road car, its lighter than that one and its fine.
i was quite surprised at the quoted weights of a standard 1.8 flywheel, even my standard french flywheel was 2 kilos less!!
the race clutch types are lighter still.

Is the engine in pieces? Then you could balance the crankshaft,flywheel,clutch and front pulley as a complete assembly. Not much point in balancing just the flywheel on its own. To lighten the flywheel shouldn't be a problem.

Don't bother with the balance part, unless you do all the reciprocating parts.
You can get a flywheel "shaved", I did it with the one in my BMW M52 engine, all the lathe op needs to do is take the metal off evenly (ish!) And the taking from the outer edge effectively lightens it more.
Obviously, don't shave the clutch face side!
This also means that any engineering shop can do this, non auto place may need a bit more guidance though.

The car and engine are complete. I'm having the tired gearbox switched for a fresher one, along with other work, and it seemed a good time to either lighten my flywheel, or swap in another lightened OEM flywheel.
I'll admit I don't understand the technicalities of milling the flywheel, although the accepted method with MX-5s seems to be shaving off an 'inertia ring' from the outer edge of the flywheel, saving about 2kg. I've always heard this done in conjunction with balancing, and that a badly modified flywheel is a safety issue. My mechanic spoke to a couple of shops local to him and they 'wouldn't touch it'...
