did my 1st AX with the 914 GT clone today Options

[rfuerst911sc]

Today I took the 914 GT clone to her first autocross. I posted here rather than the paddock as I'm just getting my feet wet with the 914. Overall for the first time out I think I did good. I was 5 seconds off TTOD and this was on 5 year old Yoko ES100's. Here's a little rundown on the car before I ask some questions.
3.0 stock 911 engine with Weber 40 carbs.
911 Front struts with 3 inch ear calipers. Standard Boge inserts.
911 M calipers on all four corners. 20mm vented rotors all the way around.
Rear Koni shocks set to hard with 140 lb. springs.
Stock 901 transmission with stock 4 cylinder gearing.
Front 19mm sway bar no rear bar. Standard torsion bars.
Car corner balanced at 2100 lbs.
16x7 + 16x8 Fuchs with 205/55 + 245/45 tires.
19mm master cylinder.

Now the questions. The car seemed to be well balanced but I really struggled with rear traction. Coming out of turns it was very easy to spin the tires. And launching from the start was either spinning in 1st gear or a slight bog starting in second gear. And I quickly found out that stock street brake pads are not up to snuff for aggressive driving. I have some Porterfield R4S that I'm going to try. So you guys that have more power than me how are you putting it down ? I know better tires will make a big difference along with me learning how to drive the 914 vs. my 911SC but any tips to pass along ?
Overall I had a blast as I always do (IMG:style_emoticons/default/biggrin.gif) .

Well yes, tires.....and maybe an LSD. (IMG:style_emoticons/default/biggrin.gif)
I could light up my 10 inch slicks launching in 2nd gear with my little 2.7L so you can't get past that, but good tires will help. You will also find that R Spec (Kuhmos & Hoosiers) tires have much better recovery characteristics than street tires. This becomes important when finding the limits of that 3.0L's traction ...challenges.

On my first time out with the 2.7, I got about 200 yards on street tires before going backwards. I didn't take it out AXing again til I had some wider R specs in back.....the next month. (IMG:style_emoticons/default/biggrin.gif)

By "recovery" I mean what you see about 20 sec. into this vid.

Heh, there are several "recoveries" in the vid. Some are more artful than others.
