There was mention earlier in the thread of Golf, TT and 5 and 6 speed boxes, so for clarity, what shafts and CVs have you got?

Presume they will be 108mm inners, but are they the six ball Rzeppa, or the Tripod type inner CVs?
Are they the nut or bolt type outer CVs?

108mm, tripod inner, bolt outer.

Don't encourage him.
Ask a question like that and it'll be another 100 posts about his plans and 20 photos of nothing of interest..
And you'll delay by another 6 months the guy ever daring to pull up to the line of


The Big RACE!!!!

In the thread: Massive overthinking.
Not in the thread: Guy with a 200hp front driver with axles that went for 20 thousand street miles with no grease and new boots were only installed after the car started shuddering horribly when changing lanes/taking bends after 2-3 hours at 75mph, still planning on driving it to Nationals this year and shooting for first place that isn't a Fiesta ST. Sorry, no build thread as such.

Car is fine. You fuck it, it just get expensive and still can't clear broad side of cone.

VW been doing this for a while, although Lobro or whoever VW sources the joints from (probably not Lobro) didn't really figure out how to do a tripod joint in that timeframe, they can get a RIGHTEOUS shudder under power after something goes all sideways in the inner and the axle starts moving asymmetrically.

Save time on the assembly line, make assembly faster, need fewer trained monkeys the easier it is to pop a car together. I think every engineering decision made at VW is geared towards faster assembly line.

David; I was able to speak with Steve Skirrow at CVJ. Thanks again for the information. I am going to send him one of the sets I have, and have CVJ do them. Then, I'll destroy my stock set, and my rebuilt set learning to drive this thing. When I put in his set, I will send the other set that was rebuilt local, to have CVJ do them as well.

6 days with no updates...

I guess the Drambuie slurper or rest of the Captain Morgan guzzlin team must either be hungover from the weekend or trying to work out how to take pics of inner CVs.

C'mon tae fuk Dan, shows us your greasy baws!

Sorry. No real updates. Blew the rest of my wheel budget. So now to mount tires, and build a tire rack for the trailer. Damn directional tires make more necessary spares than I've ever imagined...

6 - 15" x 6 1/2", with 205/65/15 DMack Grippa (used).
6 - 15" x 6", with 185/70/15 DMack DMG2.
1 - 15" x 6", with used rally tire, on-board, (for emergency spare).
4 - 16" x 7", will mount with snow tires, if I can't sell them.
4 - 17" x 7 1/2", will mount with 17" Indy F for Tarmac, eventually.

Been rebuilding the engine itself, since its out of the car. New head gasket. ARP head bolts. Hoses and belts. Coil packs. Seals. Etc...

Seems someone is too shy to shows us his baws...Although I suspect he has none... (at least in his inner cv joints).

That being the case I have had a search of t'internet and found these pics to show the inner cv differences. Tripod type on the left, conventional 6 ball type on right.

Never had one of them opened up. They develop a bad shudder and we throw new ones on, problem goes away, life goes on. Never was particularly curious enough to open one up and see what's what, have seen plenty of worn out tripod joints, no need to spend time to see another.

As I had posted earlier, this is what I have. The only axle I had that was the old conventional style was the Raxle, that I have been told by this forum Not To Use. The 5 others are all Tripod Inners.

OK so admittedly I haven't read the WHOLE thread (I think it might be an impossibility at this point actually) but let me get this straight..

You have 4 different sizes of wheels, and 21 SPARE tires, for an MF'ing Rallycrosser? Included in that list an on-board, emergency spare. I really hope this is for some future Rally plans, and even then I would call it overthinking.

I've changed a total of 1 tire on a hot rally stage(100AW snowpocalypse 2015), and 1 tire on transit, after riding the flat for about 3 miles to the end of the stage so we wouldn't lose as much time (also 100AW 2015). I've never even considered bringing a spare with me onto a rallycross course, and after the one flat I got during a run, I had enough time to go to the truck, get the spare, change the tire, and didn't even lose my place in line for the next run. Maybe our local rallycrosses are different from yours.

Adam;

Admittedly, I like options... lol.

I bought the 17" wheels with the rolling chassis, and then found out from the members of this forum, that they were not a good option for my intended purpose. That's why the "eventually" is there. Once I go up to the FIRM, and go on there european designed rallycross track (mix of tarmac, dirt, and gravel); then I will have the 17's mounted up, and those wheels will be for that.

The 6 1/2" and the 6" sets of 15"'s, give me two width options for the RallyCross events here, until I figure out which works best for me, and my car. The 205 set, I was able to purchase with 12/32 tread, for 200 per set, so it was a good financial decision to get them, versus a second set of 185's.

The 16" wheels were sold to me as 15", and were originally supposed to be for the 205 tires. Got the wheels for cheap, so "IF" I do not sell them, they will get mounted up.

Honestly, I don't want to keep the 16" wheels, unless I cannot get rid of them. They will probably be kept simply for break-in, test runs, dyno runs, and to keep the car drivable, without putting miles on the DMacks.

Getting ready to install the HotBits rear shocks/springs. Does anyone have a preferred option for the helper springs? Helpers on the bottom? Helpers on the top?

I know I have to put the reservoirs to the rear of the car, but HotBits did inform me that on the passenger side, I may need to swivel the reservoir forward, as on some years the reservoir interferes with the filler neck for the fuel tank.

I am going to install the lighter spring set for now, as that was the consensus of the board members. And I will keep the 30 Kg set for rally sprints where there may be a jump or two involved.
