    I'm going to install new SS lines in the tunnel. They have two layers of shrink rap, one red for high pressure and one green and black for return. The top picture shows a company that sells 4 foot lengths.
    I just did all the wheel bearings and added longer studs for 4 more custom 10 hole steel wheels. (Picture 2) The steel wheels require 7 mm more thread than my Fuchs.

    I thought I would update on the 2.4 POLO oil temps in my car. I have misguided folks for the last 8 years. Not intentionally. I've had a 120C temp sensor on this engine all these years. It should have been a 150C sensor. The 120C has been reading 25 to 30F too hot. I switched to a 150C sensor and the oil temp at the tank with a turkey thermometer, inferred on the temp sensor and the dash gauge all say the same. Some 25 to 30F cooler! All this sweating over 230 to 240F for 8 to 9 years was all for nothing. Currently with the duel trombones and a refreshed inline SC thermostat I see a constant 180 to 190F cruising around Denver with 85 to 95F and 15 to 35% humidity. Well see what happens when pounding 12000 foot Colorado passes. I'm guessing 210 to 220F not 240F plus.
    I don't track but I think these coolers would work fine for that.

    These ball joints come in two different configurations. One for 65 to 68 struts and one for the later wedge pin struts to use with our early a-arms. They allow for a fair amount of negative camber. So I can use the struts in the picture without changing out the whole front suspension.
    I think the early front suspension will be more desirable now that these can offer easy adjustment of front negative camber. And the option to use the later struts with 3.5 inch brake caliper mounts for more brake options like the Boxster calipers I intend to use.
    Both Rebel and Elephant sell them.

    Now I would like to figure out if I can make the early a-arms work with the aluminum crossbar. Or modify the later a-arms to work with these ball joints. I'm interested in the aluminum crossbar more for the easy access to the fuel lines at the gas tank than any weight savings.
    By the way, I use Rebel suspension bushings. They allow me to drop the crossbar in 15 minutes, and have the steering rack off in another 15. Unbolt the rack to the crossbar, pull the t bars out, unbolt the rear crossbar, loosen the front a-arm mounts enough for the bar to slide under the brake master cylinder and it's off. It makes installing turbo tie rods a snap.

    Boxster front brakes. I'm running the same cryo'ed 20mm wide Zimmerman rotors I used with the Alfa Brembo's. They show zero wear after 12,000 miles. You can run your fingernail over the outside edge and it's smooth. I'm not using the 24mm Carrera rotors as the car is light and I don't want the extra weight of the 24's. I'm adding 1mm Hard Brake titanium plates on each side to take up half of the 4mm thinner rotors.

    The struts are 69-71 E/S Koni with the spindles raised 19mm. Spacers at the steering rack will be added along with longer Turbo tie rods.

    Installed the new rear calipers. The rear brakes went from 35 mm to 42 mm pistons and about 25% bigger pads.

    The ball joints are about 2 mm wider and need hand fitting then paint. This allows you to use a LWB strut with a SWB a-arm. They also make these to connect with a SWB strut. You can dial in 2 degrees negative camber if that's your desire.

    15 inch steels clear the Boxster Brembo’s. 16 inch Fuchs have plenty of room.

    I did a Vail to Steamboat to Vail lunch run Friday with this group. Kind of a David and Goliath thing. 80% plus were very tight mountain roads. As long as the roads were tight I was able to stay with them. When the roads opened up they went into light speed. When the roads got tight again I could pull them back. 80 to 120mph back to 40mph in the tightest corners 100's of times. About a 100 miles each way. Never saw a Police car. It was a good time.
