unsprung weight
Turbo Mini Forums

good evening,

i want to loose as much of the unsprung weight as i can, any ideas? i've seen the lightweight drive flanges,rear hubs and front swivel hubs in minisport. i've also seen the force racing bits, but im not that rich!

cheers

drilled and groved disks must be lighter sounds stupid but everything helps...
light alloy wheels, ally breaks. its expencive to loose unsprung weight oh and ally rear drums :)

Searching is all you need on TurboMinis

yeah i already worked out about the wheels, the alloy 4 pots are on the shopping list too. rear discs or alloy drums too.

alloy swing arms - lighter suspension components (eg ally shocks)

i've looked at the minisport alloy swivel hubs and steering arms, but im not sure on the quality and i've never heard of anyone using them...

Wait until KAD make alloy front hubs. I wouldn't trust my life to a minisport product.

Put nitrogen in your tyres

Drill the hand brake leavers in side the rear drums.

Part original weight new weight saving
alloy radius arms 9.3kg 5.08kg 4.22kg
alloy rear hubs 1.9kg 0.936kg 0.964kg
alloy front swivels 5kg 2.8kg 2.2kg
alloy drive flanges 2.2kg 0.92kg 1.28kg
alloy rear discs conv5.6kg 9.2kg 3.6kg
alloy brake calipers 5.4kg 2.5kg 2.9kg
magnesium wheels 38kg 14kg 24kg
total 39.14kg

Racing tyres are lighter than road tyres so that would save on unsprung weight too, so magnesium wheels + racing tyres could reduce unsprung weight by 30 odd kg so keep an eye on fleabay or put out a 'wanted' ad.

Mmm, sorry that chart didn't work out too good, the spacing got all closed up went I sent it so it's not easy to read.

Yep, all the original weights are for the pair of steel components & the weight savings are for a pair of new lightweight components.
The quickest/cheapest way to save unsprung weight is to buy a second-hand set of mag allys with racing tyres, there must be loads of stuff like this in someones shed etc which they might like to turn into cash if they find some enthusiast who wants to make use of them.

I seriously doubt it!

Why can't I find something simple like alloy wheel nuts in 3/8" ?

They make them for all the metric studs.

Exactly gary, MiniSport are billet (supposedly 7075), KAD have cast theirs.
I read that KAD found a fundamental flaw in theirs which is why they have got to production, but they also said they can see the same flaw in the MiniSport ones

I seriously doubt it!

what are the flaws?

The things in your house that you walk on


KAD wont say

I seriously doubt it!

when i was over bill richards last year he got a delivery from kad. a nice set of ally hubs in the box :) i opened the box and saw them first ahaha but he tests for kad so thats why he had them :)

does anyone use the rear alloy hubs? i'm mulling over getting some

i reckon some folk should make an alloy steering rack tube! only a small reduction but it all helps

i only realised recently that the OE rear radius arms are hollow, WTF are they made from to be so heavy??? i did'nt think anything hollow should be that heavy, weighty for there size?

allso someone should be knocking out lightweight disks with alloy bells by now!

it al depends on their use dont it, KAD is KAD stuff is pricey as its strong enough for racing & road, minisport i'm unsure about as i dont know how they test stuff!

i though cnc alloy stuff was stronger than cast???

i'd like alloy calipers & s drive flanges for the front & alloy hubs for the rear

i cant afford alloy radius arms yet ( keep the prices the same for 2 years & i'll buy some

oh also someone should knock out ally steerin column tube
i suppose aly can be made of lighter materials! hmmmmmmm

SKYLINES ARE LIKE CLITS, EVERY FLANGE SEEMS TO HAVE ONE: see this sticker on my silvia

the Search-section on this forum is blummin superb & simple to use, unlike some other forums, without the search-section & the help of this bunch of chaps on here i'll never be able to !!!Start the day with a 998cc turbo!!! :) i'm getting closer though!
