Ok, so now that we have stepped up the game and have found more lateral cornering G's I am in lifting the inside rear tire again.
No rear sway (of course) High rebound rear shocks 200 lb rear coil over. high rebound koni race shock and 21mm torsion bars in front with 22 Weltmiester bar. set as much as I can before the car pushes. So looking for advise on LSD what's available and what's the difference of each in an autocross application. |

I hate a thread where everyone agrees....Iff'n I was smarter, I come up with something radical. Lemmesee.
I argee with Grant on the TB diff. I agree with Josh on the FWD cars & chassis stiffening. I agree with Chris on the parts buying. I agree with everything Joe says cept when he says he is fast.` Ah ha.....I don't argee with Chris H on a clutch pack LSD for AX, but if you must have one: Guard Transmission 888 89 GEARS Thank God, some contraversy.(IMG:style_emoticons/default/biggrin.gif) |

We've having a hard time keeping traction even with all 4 wheels planted firmly on the ground with R250 compound 9 inch wide goodyear eagles. We're going to need it at parade this year. Anyways it's not me you're disagreeing with, it's my dad. (IMG:style_emoticons/default/biggrin.gif) |

Is there a rule against that? Greg Fordahl recommend a TB diff to me and he uses one. Should you guys beat him with a clutch pack type at Parade, I may listen to your dad. (IMG:style_emoticons/default/biggrin.gif) |

(IMG:style_emoticons/default/biggrin.gif) No rule against it, but I think he knows a bit about what he's talking about. People who enlist his services historically end up winning nearly every single race in their particular series. We shall see how the parade pans out. We're going to be there for TTOD. I don't know this Greg Fordahl, but I have met Mr. Tom Provasi, and with the old hundred horse 2.0L in the blue car we took TTOD away from him at marina a couple times. Now we've got a whole lot more power, we've tweaked the car a bit, and with this limited slip I'm hoping luck goes our way. The parade is an interesting change in format for us though because it looks like we won't get very many runs, and they will be spaced way apart. I don't know whether this will work to our advantage or disadvantage, but I do know one thing: We're gonna have a whole lot of fun finding out in the hot san diego sun. That's what all this is about anyways, nobody's getting any money out of it or anything. (IMG:style_emoticons/default/cool.gif) ( except maybe the wise person that sponsors our car ) |

(IMG:style_emoticons/default/cool.gif) ( except maybe the wise person that sponsors our car ) Ihave my doubts about the hamilton being a parade winning car after running against it recently. With poor running car and very tired dot tires my car has been within two seconds. With race rubber and carb issues worked out I think my very basic car with a good driver could equal the hamilton car on a fast course. A fast 3.6 car will be my pick at parade based on seeing the "improved" hamilton car run. It would be interesting to see how the hamilton car would do on dot rubber. Typically its the only car running race slicks at our local pca events. |

(IMG:style_emoticons/default/biggrin.gif) If you're that close you should get some racing tires and show us the business. We shall see how it goes when we get some fuel injection and a limited slip, I think that the new engine is hardly doing anything for us because we just can't get the power down with the one-legger.

That Arial kicked butt with those skinny little tires. http://www.youtube.com/watch?v=iMhWt_7kGOM Then I looked at results. http://www.pca-ggr.org/acresults/041407.html ...Man tell me AX isnt all about tire grip! Was Andrew having a tough time without the LSD when he was on DOT tires? I know my car was a bear to control in low grip situations with no LSD and DOT tires. |

Was Andrew having a tough time without the LSD when he was on DOT tires? I know my car was a bear to control in low grip situations with no LSD and DOT tires. That particular autocross left everyone quite a bit annoyed, andrew and I were in the first rungroup and it was almost still raining when we were out on the track, then the track dried out and everyone else got to run for the second session. Andrew was driving my car in the morning, and the blue 914 in the afternoon with some skinny all-weather street tires. He drove my car again in fun runs and the track had dried out so much he beat his own time. Can you imagine what kind of surface difference that is, if he's faster in my car than the blue car? |
