    LOL, I'll remember that. The shop that does all of the custom Land Rover work for the N.H. L.R. club is in Eliot. Nice guy, nice shop.

    Matt Brown. I used to be in a LR club in NH -

    I haven't been in rallyx that long but I can't imagine using such a huge gravel tire. Those things must weigh 100lbs each!

    (I run a MINI in MF and I run Black Rockets in a 185x65x15 size...I'm about to order some new brakes and will get a slightly smaller size just so they still fit under the 15s).

    Very interesting. Thanks for the link. Is anyone using these Indy tires, that you know of?

    Price is reasonable, if accurate. They are retreads, so that keeps the price down.

    Mudhen; That's him. I was in SNHLR. The only member living in Florida. Back when Tom was president. Every year on vacation to visit my family in Derry, we would do a winter run. I have a huge, lifted Borrego Yellow DII Kalahari edition.

    Stage Three:

    Fitted the upper rear stress bar. Finished removing the rear interior and sound deadening. Removed the seat belts, along with passenger side front.

    Removed the stock steering wheel, and fitted the quick release hub, along with Momo Millennium steering wheel. Sourced a set of black housing Mark 4 headlights. Didn't matter much about the housings, but they came fitted with HID bulbs already, so was worth the purchase, since I needed one headlight anyways.

    Teaser; for the Build...

    My mechanic has sourced me a Mk. 1 225 HP TT Quattro. So here comes the 225 Hp 1.8T, the 6 speed trans., the quick ratio steering rack, Aluminum lower control arms and subframe, bigger knuckles, and the larger, vented rear brakes.

    The TT finally arrived at the shop. Hopefully within the next week, I can start stripping and inventorying what parts to use. I know I will be using the Audi aluminum subframe, aluminum front lower control arms, Audi 225 AMU code engine, 2.5:1 steering rack, steering knuckles, and rear vented brakes. The "Maybe" list includes the transmission, and various rear suspension pieces. As its a Quattro, I am thinking right now that only the rear brakes will be able to be swapped over.

    With this set-up, stock at the crank was 225 set up for Quattro driveline. With FWD, and only FMIC, intake, and exhaust done; I will still have 200+ to the wheels. I may run a full season like that, to see where my weak links will be, and once those are addressed, do the tune to 280+, with around 250 at the wheels. One thing I remember was once your weak links are taken care of in a race car, you only end up finding the next set of weak links.

    Sounds like a monster. Stop wasting time on the car and figure out your picture-posting issues!

    Sorry about the lack of updates. The inability to post photos on this site has been very frustrating...

    Stage Four:

    The strip out is done. Gone is the stock AWP code 180 Hp engine and the stock 5 speed. Now to cleaning up the engine bay of everything that is Not needed. Going to relocate the battery to the trunk. Thinking about removing the A/C system, but not sure since I am in Florida after all.

    The rear 337/20AE valance has been removed. Decided it hung down way too low, and would just be a sand shovel on the rear bumper cover. Now have easy access to rear tow point as well.

    The rear suspension is being set up. Went from a stock GTi rear sway bar to the solid 28 mm Neuspeed unit, which is adjustable. Set it to full hard for now, hoping to make it easier to rotate the rear around. Removed the front sway bar at the advice of many VW rally and RX drivers.

    For now, using VW Jetta station wagon springs for additional height. About 1.5" over stock ride height. The car came with Koni coilovers, and even at full height, it was still sitting about 1/2" lower than stock. Just have some junkyard shocks in there right now to keep it as a roller. Stage one will be either Bilstein HD or Koni units. Was thinking the Str.T series until I read about their Special D version which is rebound adjustable. At less than $50 per pair more than the Str.T; it only makes sense to have adjustable rebound.

    Rear suspension question:

    Instead of spending the money on the Bilstein HD's, and then after only a season or so, replacing them; I am thinking of just biting the bullet and going with the HotBits suspension. Its expensive, but at least its in my budget.

    With the rears, the OE travel is 235mm, which is 9 1/4". HotBits shortens the travel to 219mm, or 8.6". Does this make sense to those of you that have run solid rear beam VW's in competition. Will this be enough travel? I know I'm building for RX, but if I do decide to run a couple of Rally Sprints per year, I want to be able to do it on the same suspension at this price point.

    Thanks.

    The front end repairs are done. The front bumper cover has been clearanced for the front mount intercooler. The new headlights are in. Removal of the A/c equipment has now turned into tracing, understanding, and removing a bunch of the emissions equipment as well.

    This coming Friday and weekend I will be researching my transmission codes to understand the ratios, to see if I can get away with one of the 5 speed boxes I have accumulated in its stock form. I am hoping one of the 2.0 4 cylinder golf/jetta boxes I have has the 4.235 final drive in it. That would definitely help spool up the turbo earlier, and I can leave the wide 4th and 5th alone for if I do Rally Sprints later on.
    Also, at $100 or less per box, I can keep a spare or two always in the trailer, without it costing a ton.
