Motorsport Wheels

[SBK930]

New wheels arrived,

Test fit has raised a couple of issues.

Front..16x9..........fronts are a little past the guards. To fix this would the best option be to swap out the spacers for a pair slightly thinner ??? Any suggestions for thickness ???

Rears...16x11........found that the rears are hard up against the fins on the rear brake calipers. Would it be possible to remove some of the height of those fins to provide space ?? Or use small 10mm spacer ???
Also the studs are far to long with spacers removed. So can I replace the studs ???

Thanks.

Loving the new look.






Wheels that came with my 930 look a little tired and centres need re-chroming.

I simply cut the rear studs on mine, when I went with the Fikse wheels that eliminated the stock thick rear spacers. I would not machine on the calipers, spacers are your best bet.

What year is your car? If I recall correctly, only the very early year cars came with factory removable front spacers.

Mine is an '84 and there are NO front Spacers, the wheels fit right onto the front spindle hubs.

Hi mark,

1978 930.

Has removable front spacers measuring 47mm thick. The issue is the bolts are small diameter and I have to remove the dust cap I think it is that is covering the bearings to remove the spacer.
I think that is what I was looking at.

Pic of the spacer you mentioned? Usually thick spacers are nut secured to original studs and have their own studs for wheels. After you remove the adapter you can change the original studs guite easily on front. Or is the senter hub cover blocking the nuts somehow? That might leave marks on the cover when you need to pry it out.

[SBK930]

Hi smurfbus.
I should have taken a pic of the front spacer.
It is bolted through the rotor and had to use a 13mm socket on the nut and bolt, which loosened the rotor but the spacer I could not remove unless I remove the cap on the spindle.

[smurfbus]

Ok ,thats reasonable. But can you pry the cap off with the adapter on? Maybe the cap will come of with some force on the adapter? IIRC it was just press fit when I adjusted my bearing.

[SBK930]

Hi smurfbus,
Cap has a threaded center.
Looks as if it designed for use of a puller.

[SBK930]

I will remove the front wheel tomorrow and take a pic this time.
Biggest problem is that I can not find any spacers here on pelican that will do the job. Must all be for later models.

I have a 79, when i had the wheels built i mocked it up with smaller spacers front and rear, the factory spacers on the front are not bolt on, they slip over the studs completely, i chose not to cut the studs shorter but instead to run open lugnuts and just let the studs poke though alittle, looks kinda race and if you ever want to go back to stock wheels and spacers you wont need to remove the rotors and replace all the studs. H&R trackrite spacers come in a bunch of different sizes and the lug pattern is the same all the way into the 996 and probly even later, i have a set of. H&R 46mm, 23mm per side for sale in the classifieds if i remember correctly the stock fronts are 28mm per side, if so 23mm would set the wheels in 5mm more per side.

[SBK930]

That’s interesting RDG,

As my front are bolt on and appear to bolt onto the rotor. The rears however do slide on over the wheel studs. Like you I do not want to shorten the studs because I will need to put the wheels it came with back on each year to pass registration laws.

SKB,

You can use a step drill to drill through the end of a standard lug nut. I did this for the rear wheels when I installed Fiske wheels. Just have to carry a deep well socket with you depending on how far the stud sticks out.

You could have the front spacers machined a small amount. Reducing the spacer thickness also reduces steering effort. I carry a standard spacer for the rear with me in case I ever need to use the spare tire.

[SBK930]

Great point regarding the spare dap930.
Thanks.

About wheel lug nuts. If you get the steel ones that are used with the spacers and also required for racing. be carefull which ones you get. There are some that are longer than others. So if you are using stock studs with the longer type of nuts you can fail the tech inspection for not enough thread protrusion of the studs through the nuts. If I remember correctly it was 3 threads. my after market wheels have slightly thicker centers and I had swapped over to steel lugnuts for the track. Fortunately I had two different sets and the track was close to home. So I drove home real quick and swapped them out.

[RDG]

When you say the fronts bolts on do you mean with one small retaining screw or do they bolt on using all five lug bolts, if in fact bolt on with a five lugs i dont think thats stock and somone musta added it to the front and cut the studs at the same time to make them fit, if thats the case i would remove and replace studs with the longer stock ones and get the right thickness slip on spacer to fit. I know people run them but i wouldn't use a bolt on spacer on any kind of performance car, IMO. And as far as i know all 78-79 930 with the full floating brakes in front had slip on spacers.

[SBK930]

I could not find what I was looking for so spoke to Glenn at pelican.
This has helped me realise what I have been calling a spacer is actually the hub.
So my bigger issue will be that there is not a narrower hub that I am aware of.

These wheels were fitted to an early 70s rsr type car. So the front set up must be different than mine. But was told they should fit.

[Rawknees'Turbo]

Dayummmmnnn Steve, I really like those wheels. Who makes them, or were they a one-off custom using Fuchs centers? Looks great being as they are still 16s but super wide!

[RDG]

It appears that your front rotors have been replaced with the later 80 on non floating type, over the years the floating front rotors were very expensive and some probly replaced with the later stuff that was avaible and costs less. If this is the case theres no trimming or machining that can be done, only option is different offset or thinner wheels up front or find and change back to the floating system that has the removable spacers.

[SBK930]

Hi mate,
Not completely sure who made them rawknees.
I think they are early DP Motorsport custom wheels.
But you are right they sure got the sexies about them.

[SBK930]

RDG that is some great information.
I will see what I can find out about the floating rotors and assembly.
Maybe my only option.
Thankyou.

Will take some pics today.

If your "spacer" looks like this and the rotor is bolted it via 5 bolts with nuts....well that is no spacer...that is your front hub that contains your wheel bearings and seals, and that is not easily modified to get what you are after. That is not the same as aftermarket or factory wheel spacers.
