how to modify the wheels
 

Ok guys i may be the only one who is having problems with the real wheels coming loose after each round. I raced at the weekend at southport outdoors ans after every round the rear wheels had become loose and caused the roll pins to shred the inner wheels centres.

So today i have been looking for a solution.
1. problem 1 the roll pins are way to short 7.5mm
2. the wheels are too deep in the centre hole
3. The wheel spacer are too shallow

solutions
1. I used cat sx roll pins they are 11.5mm long the same length as the the slots in the wheel.
2. If you look at the depth of the holes in the rear wheels you will see they dont leave much thread for the wheel nuts to fasten too. this in tern does not allow the nylon on the wheel nuts to grab the thread. so i used "rev-lite" schumacher wheels.

3. the rear wheel spacers incorporate a small thin crunch spacer in my opinion it would be a good idea to make this a deeper spacer so as to take up the space on the rear axle.

I also couldn't work out why they decided to use hex fittings on the front. ?

so the next mod is to use the front wheels spacers and roll pins from the cat sx this allows you to run cat wheels all round :) happy days no more gluing your own wheels.

if you dont want to use the original wheels just use the roll pins and buy some
shallow nylock wheels nuts.

any questions please ask i can send pics if it makes more sense.

p.s this is not a moan about the car i think its amazing great car to drive.

Personally i just changed from nylock wheel nuts to serrated nuts and they have been fine :)

The front hex/rear pin combo is pretty much the industry standard in 4wd so its the obvious choice and gives a bigger selection of wheels to chose from ;).

Personally I've not had any problems with the rears?!?

I have about .5mm sticking out from the rear nut. Can't see why yours doesn't have enought for the nylock to grab. Strange.

chris had this at the weekend its just that the roll pins are way to short, use some solid metal ones as long as the slot in the rims problem solved

Agreed, use serrated wheel nuts and use solid rear pins, also use associated shims to push the gold plate closer to the pin; so the pin doesn't bend as you tighten the wheel up.

I assume you havent had the car in a BRCA width box yet? you will have to use serrated front nuts and dremel the driveshaft thread protruding through the nut to pretty much level with the nut head to be BRCA width legal.

Could someone post the part number for the Associated shims and the serrated nuts.
