Lightest Alloy Wheels?

[anonymous-user]

Hello again everyone!

After giving my Cayman 987 a full service (ooh er!) over the Easter weekend I got to thinking about what else I could do to further my enjoyment of the car (which after a decade I still love).

Wheels, I started thinking about wheels. But specifically, what are the lightest wheels that would fit the car? 17” or 18”, I don’t care - but I assume 17” would be lighter.

Does anyone have a list with weights and fitments? Anyone been through this process before?

OEM or reputable after market - I don’t really care about how they look. Oh, and something I can reasonably afford - I’m sure there’s hand woven, carbon fibre, unobtanium wheels out there 😂

Thanks!

OZ Ultraleggera and Team Dynamics Pro Race 1.2 used to be the go to light wheels at a good price point.

I’ve heard that, thanks. Is there a listed weight of either of these wheels though? I’m finding it really difficult to find solid data.

Essentially I don’t want to spend all this money to only save 100g per wheel

Some good info here if you’d rather stick to OEM wheels.

Not a massive difference in weights though.

Don’t forget the check tyre weights too, no point saving 2kg a corner on wheels if you’re adding it back on with the tyre.

You don't care how they look??
A set of st looking wheels fairly ruins a car.

Not if you paint them black! Cant see what is there.

Not really. I’ll be inside the car so I don’t care

But there is the hub, disc, calipers, etc., that still add to the unsprung weight. And dropping from 18” to 17” still adds a bit of tyre weight (ride comfort may be better though).

This is extremely interesting, thank you. Seems I already have the lightest available for my fitment.

Tyre weights, now that’s something to think about. Thank you!

If it’s adding enjoyment you may find a good suspension set up and uprated brakes (or even just pads if keeping cost down) makes much more difference.

Unless carbon or magnesium wheels you’d do well to notice the difference in unsprung weight between Porsche wheels and another alloy…. And even then probs not much.

As ever it depends on how much you're willing to spend but on what is a relatively heavy car with relatively light OEM wheels anyway, anything modestly priced isn't going to make much difference.

They have a weight table.

A 7 x17 wheel is 6.29kg.

Anything from Rays Engineering will be light, and strong. Not cheap though and have huge waiting times for delivery!

Personally I think the stock suspension is incredible- especially the damping.

I think you’re right tho, there’s minimal difference in weight between my current setup and what on offer. I’ll look at lighter weight tyres next time.

These do look great, similar to what I’m running now

These, in the bronze/gold colour are especially lovely

This might give you some ideas, Elise owners can be pretty anal about weight and the rears of the S2 Elise are 17 inch (albeit I think wider than the standard 17 inch 987 wheels, which will obviously push the weight figures on the Elise up a bit compared to what you'd buy).

I think this is a good call.

Those Porsche wheels look well optimised. Bet they have been tested for cooling and durability on your car too. Not something OZ could achieve with aftermarket wheels selling to all and sundry.
