Minilite on 3.2

Out of interest, both Minilite and Fuchs came back with weights for their wheels, as below.

Milinlite: 7" 12.0 KG,    8" 13.5 KG

Fuchs:     7" 5.6 KG,      8" 5.85 KG

I think the subject of the weight of Fuchs is as contentious as which oil to use
 

Those figures for the Fuchs do seem light for 16”x7/8

 

Im not sure of the veracity of this chart as it’s been around for years?

Looks about right, quite a difference

On my 964 I've stripped out over 200kgs,  biggest single difference I felt driving was the weight I removed from the wheels

Was a huge eureka moment, despite a lifetime of saving weight on super road and race cars 

It transformed the driving/steering feel. Less rotating inertia,  gyroscopic effect to the steering and unsprung mass transformed the acceleration, steering and grip

The 10kgs I saved on the wheels felt the same as the first 100kgs I saved on the chassis

 

Ditto when i ran some 7" cookies for a while, the car felt like a young Bambi dancing through the lanes as they were so light. But on track when pushing on i really felt the lack of 'girth'..ooer, and the back would skip around a little too much on the edge when chasing Longers full pelt !

Think i have a pair of 7x15 Fuchs in my garage that feel super light, so may one day drop back down to 15's but finding tyres is more of a pita.

Its a shame those minilights are so bloody heavy, dont they make the light 'mag' versions anymore? I know they are robust for rally use primarily but look great in a ST style.

I do love the Campags, but unless you can run a wider wheel, they can look a little flat on a narrow body. Absolutely ace on a widebody though:

From my archives of lightweighting tomfoolery...

In 1999 we ran a 12 lap qualifying only F1 car

It used race spec. magnesium rims that only had a 1500km life before the spokes cracked but we lightened the qually only rim further by machining the barrels down to 1.9mm thick

Touched a kerb and they turned into an egg shaped wheel

Can't remember if they were chucked in the bin after 12 laps like we did with the magnesium qually only engine heads

could always go full 'ST' look and put lightweight fuchs on the front for light steering and a set of Minilites on the back, where the extra weight wont make as much difference, in road terms use.

A PO had painted mine gloss black so ended up buying new. If yours are in good nick then the matt black matches the petal finish perfectly (presuming you've gone for black). It was a leap of faith as I believe I was the first on here to go for the new build Fuchs (there's a post on here somewhere), but you won't be disappointed as they are as perfect as the originals; they have the Fuchs stamp and only difference is the lack of a Porsche part no stamp - for that I guess you'd have to pay the Porsche tax which seems ridiculous.

I have just purchased a set a new 7&8 x 15 RSR finish Fuchs from Rose Passion in France and the wheels arrived in the UK less than 48 hours after placing the order and they are are great company to deal with.

The quality of these forged wheels looks excellent and I can not see any variation in design to the 40 year old Fuchs I already have. Checked them on the scales and each wheel is around the 6kg mark so nice and light.

This weight business has always interested me and 12kg for a 16x7 minilite seems a lot. Anyhoo, I traipsed off to the shed this morning and weighed one of my spare 15x7 and it is 8.8kg. An extra 3.2kg for what would be essentially an extra 1” diameter of the centre can’t be right? Also, there is a difference of 1.5kg between the 7 and 8 (above numbers given) so surely that would be the same or slightly less between the 15 and 16? Unless they have drastically changed their design and/or materials.
