I started modifying my car a few weeks ago for autocross. It's a 1973 1.7l car with a more or less stock 1975 2.0l engine, very clean. After the Portland PCA AX #1, I made a few postings and got some suggestions. Rather than continue to hijack that thread, I thought I would start my own.
So here's where we are at today: Tarrett Engineering front sway bar installed and set to mid point 225# Rear Springs and perches Koni Sport Adjustable Shocks set 1/2 turn from full stiffness Turbo Tie Rods 205/50-15 Kuhmo Ecsta XS Tires Empi 44mm Dual Carbs (replaced a single Weber) Mallory Unilite Mechanical Advance Distributor JWest RennShift side-shift Triad Headers and Exhaust System - heat disconnected of course Porterfield R4-S Brake Pads - to be installed next week I think that's about it. Damn, she drives nice. Super tight in the corners. Wow. So, what's next? Besides just drive and compete. I know that. I don't plan to miss a single autocross opportunity in the Portland area. Pictures next. Don't complain yet. Would love to get more ideas and suggestions. Thank you, Steve |

Yes, understood. Tires are key.
But, this driver needs lots of work too. I've got a few AX events to do this summer to try and improve the driver portion of the equation. What's the ideal wheel and tire set up for the SSM class? Street legal. If 5 lug hubs? How should I go about conversion? Seems like wheel choices are very limited staying with a 4x130 bolt pattern. |

But, this driver needs lots of work too. I've got a few AX events to do this summer to try and improve the driver portion of the equation. "a few AX events..."? Well, it depends on what you mean by a few... Less than a handful? Or less than 50? I know people who drive nearly EVERY weekend of the summer season. I'll echo what others have so wisely said. Nothing will lower your times like experience. Do some basic prep to the car, and then get out there and drive. Don't change a thing. Just drive. Drive. Drive. Drive. Enter as many AX events, schools and Test 'n tune events as you can. The more experience behind the wheel you have, the better you'll be able to judge the merits of different changes and mods that you may or may not want to make to the car. Take the oportunity to have hot shoes drive your car, ask if you can passenger with them. If you're fortunate to be offered other cars to drive, do it. I learned more in a couple seasons co-driving other cars than I did in the half dozen years before that. I learned what I did and didn't like in the way a car behaved. I learned what a truly properly setup car feels like, and I learned what even a small change in said car can do to the otherwise great handling. You're building a car that will most likely compete with the "trailer-riding-fire-breathing-monsters", so be prepared to be under-prepared. Classes with near limitless allowances tend to become ridiculously expensive very quickly. Spend your money wisely, and start with getting seat time above all else. -Josh2 |
