The Project Pad

Man those F5 diffs get about

Nice work as usual Derek. Now i am really jonesing to get back in my shop!

Do my eyes decieve me, or did you just redrill your stock hubs to get the bolt pattern you wanted on your hubs?

Makes me wonder if I can squeeze 5x100 into mine... As I have a set of super sweet wheels and brakes I could use if possible... hmmm I might have to take a trip the machine shop!

Nice work D!
Suggestion:
for the front tab on that fabricated subframe,weld a plate below to join the 2 pieces more securely rather than a bead weld.

Your eyes deceive you. Those are rather modified by the addition of a backing plate and machining to both for this to work. You cannot go to 5x100 on an Audi 4x108 hub. Take a look at the back side of the hub some time, it has several thin areas where strength was not an issue, or rather where there are no bolt holes and threads.

The box tube section on the front for the SF mount? I can see plating the inboard (vertical-open) side but not the bottom.

i'm not done yet man i gotta fab up the control arm mountings so that the thing can be put up in the car and be used, then get the final diff position situated and the brackets for it. the rails extend out the back so i have some place to put rear sway bar brackets.

And why not?

two words... YA HOO


285/30/18 is a good deal shorter than 265/35/18.... and more square... and fit my car much better you know that feeling when you score a touch down and you pull your arm down and go " UUHHHH" .... i did that


about an inch shorter over all, but about an inch more contact patch on the ground



and in comparison to my old ronals, they aren't so much in the way out at the fenders..

turbo twist with 285/30/18

ronal with 215/40/17





285/30.....


vs. 265/35....




now with the 285's, i can turn the wheel and tire just about all the way as far as stock without hitting anything inside the wheel well 8) and i still have a trick up my sleeve for .5-.75" more clearance up front by just pulling the front edge of the fender out a little. the stock plastic fender liner holds the fender where it's at, but if that's modified.... mmm, a touch more room is available and greatfully recieved 8)

stock tires are wieny sized!

Because it wouldn't add as much rigidity as enclosing the open side of the tube.

Hey Derek, any thoughts about modding a 4x108 into 5x108 and then doing 5x108 to 5x112 or 5x130? Would that be a worse idea?

Eric

Wow, nice progress Derek. Looks great. Very inspirational.
Having that much rubber on the road will be sweet.

i could probably build whatever you like using this method... one hole will always interfere, but i think i might have a solution for that.


thanks Mark! i'm looking forward to driving this thing with this much rubber on the road

i saw some porsche turbo twists up on audifans coming out of sacramento. tell me youre not bailing on that idea!

you mean the four fronts that i'm not using? yeah, those are mine... wanna buy em'?

Back to the topic @ Hand.Derek you redoing the front as well?

:-)

going to need 2 big turbos on your v8 to light those big meats up 8)

a little doodle of taking the idea further...

why not machine the original hub down smaller than the diameter of the old holes (or new bolt circle if going smaller) and thinner to accept a plate on each side and make 2 plates (possibly identical pieces in front and behind)

this way you could drill for various new bolt circles and have new metal around new stud holes...

you would probably need to "pin" new plates to old hub to make sure they could not spin on you... or maybe use countersunk machine screws like the ones that (used to) hold rotors to hubs...

just a thought

<edit> could probably make a single plate with a smaller inner hole and make it work too

yes... engine/trans needs to go back 1" and down 1". the front suspension points need moving as well, and i'll be incorporating the new front subframe as an engine/trans cradle like the newer audi cars. plus it'll be a little more tied into the frame than the stocker for rigidity.

hey Derek, is that going to have the power to turn 4 of them? :bashtard:

it'll have just enough power i'd rather be a little underpowered but be able to keep my speed in the corners 8)

Amazing stuff Derek... I am very impressed. Interested to see what the final product looks like. For my rs2coupe project however I'd like to stick with OEM bits to get her rolling...but I definitely want you to working on her. Parts are still coming in so I'll let you know.

on topic; your 4k is looking mighty brutal :wink:

You're doing what Audi should have done 22 years ago.

Eric

I'm going to be honest and say at first I didn't like the idea of the twists. Just not a big wheel kind of guy. But now seeing it in action -- almost, it looks effin awesome. And you can't complain 280s 8)
