Interesting springs.
They do not appears to be as progressive rate as the 140 lb ones I put in Abels car. Those had a significant different in how close together the coils were are the bottom of the springe versus the top. Depending upon two things, you should be able to plot out the ride height. First, overall spring height versus the stock springs you already have. Second, the spring rate, which will increase as the spring becomes compressed... For that set of input numbers you may be better off getting that from the manufaturer...should not be consistant for either spring...but should spike more on the 165 lb springs. rich |

So I need to calculate the preload for the 100 lbs. springs from the free to the installed length, then calculate the load from the sag. Add the two togehter for the total load. Then Calculate the preload for the installed 165 lbs. springs, subtract that from the load and calculate how much they will compress by the left over load. easy-peezy (IMG:style_emoticons/default/wink.gif) |

So I put the 165 lbs. mystery springs on and discovered why it was leaning so far with what I had on it!
When I was assembling the Koni's with the springs I noticed I didn't have the snubbers. So I figured I would have to take them off the shocks I was taking out - but they didn't have any either - LOL! (IMG:style_emoticons/default/laugh.gif) That's the way it came and that's the way I've been driving it! The good news is the 165 lbs springs went on without spacers and without having to compress the springs any more than you could do by hand! (IMG:style_emoticons/default/biggrin.gif) Next AX is tomorrow - wish me luck! (IMG:style_emoticons/default/aktion035.gif) EDIT: Where can I get the snubbers - I don't see them on Pelican? |

The bump rubbers shouldn't affect the amount of body roll. They are there to prevent bottoming of the shocks, which damages the internal valves. |

At a minimum you need a few plastic washers on the shock piston to prevent the shock from bottoming out.

There were some fast cars in the novice class, so I didn't place.
That said, I had more fun driving this car today than I have since I've owned it! Yes it had a good amount of oversteer going at times, but it was much flatter and could be steered with the throttle for the 1st time ever. I was probably only a little faster than before, but they set up a real open course - about as fast as you can go given the confines and still have mid 30 second runs. I think I would have done better on a tighter course like the ones they had been running (IMG:style_emoticons/default/dry.gif) So yes I need more front sway bar, but I finally have a car where changing airpressure actually has a noticable and tunable effect. I swear it pushed so bad before with just a stock front bar that no matter what you did with the air pressure, the chassis dynamics never really changed or just got worse. If any good (or bad) pictures surface I will repost here. I also love the way the new 165 lbs progressive spring and Koni reds work on the road. I swear it rides firm, but better than before and nver jaring. (IMG:style_emoticons/default/driving.gif) Chris I have one plastic washer on each side. How many should I have? Scott |

From today - on the gas heading down the back "straight".
Yes, I am turning (but not as hard as the last AX). Attached image(s)

So I am looking at options for making my front sway bar adjustable, but if I happen to come across a used adjustable bar for sale - what size is the right bar for me?

I would tell you to get a 22 on its softest setting but only if you plan to keep modding the car. If you are going to stay close to your current configuration then get the 19mm. It may be worth it to spend a little bit more and buy a setup that the bar can be changed as the car progresses. |

Never say never, but in the next few years I don't see going much beyond a 2056 engine, 205 tires, new front inserts, bump steer kit, maybe stiffen the chassis... I like it more than ever as a street car - not looking to change that. I want to build in adjustability more than all out performance. |

A 22 swaybar may be a bit much for the 165 pound rear springs. Which torsion bars are you using?
