American Rally 86 UPDATE

[COLOR="Red"][SIZE="5"]Ok, here's what im doing to get my seats lower. As you can obviously tell, I chop giant hole in floor... and insert new floor pan i bent up.



I took my LSD apart, time for a rebuild and some shimming



And a random pic of my stitch welding. This is with my TIG PS on the A piller

Ok, so the pics have captions now...

Basically lately there has been a lot of designing and not so much doing going on. The cage is sort of in limbo, and may be getting redone.... again.... But hey, soon I'll be able to build the engine!

Man i forgotten this project

oh that is so HOT, what are the rules with suspension mounting in your rally regs?

so very jealous.

Brake stuff came yesterday... and I got around to tigging the brackets to the rear end. Oh, and the cage is more completed. Pics soon, tonight if photobucket doesnt hate me.

OK, here are the pics!

Tig'd on 4 link brackets...



The brakes.


I'll be using those for the front, and stock supra axle brakes for the rear. That gives me slightly less then 50/50 bias (towards the rear) so then I'll just dial in the braking I want with the limiter and balance bar, and be good to go.

I also bought one of these...

Here are some pictures of the cage so far. The door bars, the upper half of the sill bar, the A pillar support bar, and the main X/harness bars are not welded in yet. This is so I have an easier time getting around inside the car to install the seat mounts and covers for the 4 links. Hopefully next sunday the car will be getting its logbook, meaning the cage will be DONE. Finally. Its been long... and hopefully its drawing to an end.






More to come.

Oh, I also ordered a ViPEC ecm from Bob and will be running that

Double OH, Koyo Radiator came too. Well, and I guess technically the master cylinders TRIED to come... but they sent the wrong ones... so, hopefully the RIGHT ones get here soon. then I can start fabbing the pedal mods...

Heres the difference in brake diameters.




Ok, so in order to get more powerful brakes with an increase in heat capacity (thermal mass), I had to get different calipers and rotors. The thermal mass part is easy, a wider disc, or a bigger diameter disc, or both. However, because a larger diameter disc will also effect FR RR bias, I didnt JUST want to get some massive disc. Besides, this being a race car, why should I care how cool it looks? lol. Anyway, another consideration was the wheels I want to run. The rallies here are run on gravel, so clearance around the outside edge of the caliper is important, otherwise you eat the calipers faster. All of this went into deciding a caliper to use, and a rotor diameter.

I choose the powerlite because it would fit well, and a 10.04 rotor because, well, thats the closest rotor I could find that I could make work without having to buy expensive AP 254mm x 20.1mm rotors. Even though thats the size I was aiming for. We found rotors from a camry, I think it was that were 10.04in in diameter, and .86 in thick. The problem was not many rotors that bolt to the back of hubs are small enough, and the ones that slip over the lugs are the wrong bolt pattern (as in this case).

So... I threw it on a bridgeport and bored my own 87mm bolt pattern in it to bolt it to my hubs, and bored out the center hole so it would FIT on the hub.


Insto rotor for 35 bucks.

The rear of the car has the stock supra rear end rotors and calipers. The rotors are a 10in disc as well, but only .38 wide. Plenty, for the rear brakes.

The front calipers are a 4x1.38in piston and the stock supra are a slider with a 1.6875in piston. I dont remember stock sizes... they might be in my other post.

The other cool thing is by using the stock supra rears, they are iron, and the gravel wont eat them as fast. Good for RWD. Also, I can use the stock parking brake and not have to figure out how to make my hydro handbrake lock, haha. (Fun fact, the STI I crew for, its parking brake is a bungee cord from the handle to the steering wheel.... 75k rally car... and its got a bungee cord, haha)


More Cage pics

gorgeous cage there

[dazed_driver]

Thanks! Its my dad's and my first shot, haha. We did rebend the half laterals though... haha.

I'll never do it again... too much work... Its not even done yet.

[dazed_driver]

Oh snap!




Standby for door bar pics. Both continuous bars are in... And soon one of the lower bars. A few gussets are made.
