Alignment Specs anyone?
Does anyone have wheel alignment specifications for the SPF MkIII ?
Between the 460's added weight and 275 17's up front, it's a brute wrestling the steering wheel. A friend's shop has a great computerized machine that I can use... TIA :JEKYLHYDE |

You might want to call Dennis Olthoff (704-647-9924) to ask for his suggestions with the big tires and heavy engine up front.
I do not think any alignment will reduce the amount of force necessary to turn the steering wheel. You could: 1) Get a larger dia steering wheel 2) Increase front tire pressure 3) Power steering http://www.secondstrike.com/SecondSt...erSteering.htm I am definitely considering the power steering this winter and I have smaller tires and a lighter engine! |
I have a small block and run 275's up front for Auto-cross. I put the power steering unit on and what a difference. It's a little pricey but nice.

The more positive caster the car has the harder it will be to turn the wheel but the better it will return out of a turn and will be more stable on the road. About 4 degrees positive should be a good compromise.

You guys need to hit the weight machine and eat your spinach :LOL: .
Low speed turns (i.e. u-turn) do take a bit of effort. I can definitely see the benefit of power steering for auto-crossing. |
Thanks all for the suggestions.
I did look into the power steering add-on when it first came out. But I thought I should do the alignment to specs (especially castor) before doing anything dra$$$tic. I think castor may be set too high. Dennis O. has helped me in the past with brake setup for track work. I'll give him a call. I've tried higher tire pressures. Running at the correct 25PSI, the 17's and the 425# springs make it a pretty wild (bumpy) ride with very little steering effort improvement. So, I keep it at 20PSI. Maybe higher tire pressure and lower shock dampening adjustment? Haven't tried that combo. I put on the top today and went for a nice ride. I forgot how ugly that top was! And how all the squeaks and rattles even out the reduced exhaust noise...:LOL: |

Let me know what Dennis says about alignment vs what is published in the owners manual. |
