Currently having some bearing issues with converting GTi hubs to Swift Sport hubs. Non std conversions are great arent they.

I guess I should have checked the old studs first as I knew they weren't oem.

Installed the front struts but when I checked them I could get a wee bit of movement from one. I traced that back to the spherical bearing in the top mount. I guess while I'm ordering ARP studs I might as well get a couple of COM12 bearings and replace those as well.

Finally some progress, strut bearings are replaced and Lexus IS300 ARP studs pressed in. These are a good option if you have a hub with flogged wheel studs. The knurling is 14mm ( for a 14mm hole ) so you can take the stud holes out 2mm and use these if required. I have a spare hub that I'd intended to use the Honda 12mm studs on but one hole was worn so the stud was a loose fit. I took that one stud hole out to 14mm and used a Lexus stud in that one and Honda studs in the remaining 3. Both the Lexus and Honda studs are 12x1.5 thread so it's a good option for repair. I now have 3 usable hubs, two with Lexus studs and the spare with one Lexus stud ( lucky they come in 5's ).

I'll get a photo of it just as soon as I've got the front suspension back together and it's rolling again.

With the hubs back on that just leaves sorting the front brakes. It's no quite what I was expecting. I have very little clearance between the rotor and caliper attachment mounts on the upright.

Even with low profile cap head bolts there's only about 1mm between the bolt head and rotor. The caliper would just about work bolted up as is but ideally needs to be about 1.5mm in horizontally and about 3mm out vertically. Unfortunately the rotors are one piece 262mm items so I can't make up a new bell. I guess a spacer behind the rotor would do the job even if it's less than ideal.

I have 7mm spacers behind the rotor Sam. Only because I wanted to keep the zenoli slotted discs. It works fine. Once it’s all bolted up it is solid. Then I made less spacers for the outside as fitting the gti hub onto the swift uprights meant I lost wheel track hence why my rotors were closer. So it’s 7mm between disc and hub....then 8mm between disc and wheel.

Thanks Glenn, mine seems a little different. With the open back Wilwood calipers it looks like about 3mm would be the maximum spacer under the hat. I think my wheels have less offset ( 38 ) than yours so maybe 3mm under the hat won't be far away.

The rotor is also too far through the caliper so the caliper needs to move out by 3mm. I think I'll just replace the radial mounting bolts with studs and run 3mm of spacer on the studs to adjust the caliper out. If you're running new swift calipers then I'm guessing they probably negate the need to do this.

Yup I’ve got the Suzuki sport calipers...another reason my spacers will be different

Well it took more than I thought. I decided to fit a steel spacer in place of the wheel and torque that up and measure again. That measured 6mm. So I turned down two 3mm spacers that I already had so that they'd fit in the bell and did a trial fit with both in one side. That seems fine so I'll check the other side and then make two 6mm spacers.

After another measure I decided 5mm behind the hat would be closer so I've turned down a 5mm spacer for each side and fitted those. My idea of using studs in the brackets to mount the calipers turned to crap. I set the first one up only to find that the recesses in the calipers are only big enough for a cap head bolt. it's not possible to tighten down any kind of hex nut on the stud. I guess it'll have to wait until the next trip to town and buy some longer cap head bolts. I've mounted the caliper with the existing bolts but with 3mm of spacing it would be safer to have longer bolts.

Apart from the lack of cap head bolts it looks good.

All back together apart from a wheel alignment.

Good question, should be doing the two sealed sprints that are on this weekend but it conflicts with the daughters MTB racing. Would do the sprint at Waimate at Labour weekend but that also conflicts so looks like it'll be Hawkswood sprint in early November.

I really need to test it somewhere. It'll be interesting to see how different it is to drive with the Gripper rebuilt, Koni's installed and new swift uprights. Might reduce the rear toe as it shouldn't need as much on seal as it had on gravel.

Mate thats one of those super wives. Mine only has cables and the hold is a bit weak. I can buy pretty much anything and get away with it. If you install that hydraulic wife....that's it...your done. 8-[

Unfortunately it's only temporary while I work on getting the workshop in a usable state.
