    Rick,

    What's the story with the Pro Shock 9" springs. Is this a special order that needs to be routed through Unique, or will Pro Shock do this for anyone directly? I take it these are black powder coated and not chrome?

    Thanks,

    Gary

    Gary,

    You are running a 550 LB spring, Right?
    I would be interested in the same if not heavier. I am running a big block.
    I am signed up for an Solo class with the SCCA on 8/5 in Frederick.
    I have the spacers in right now and it is an improvement.
    I might put in a couple more spacers but that starts to make the spring pretty short.
    I am in England right now and will be back the 30 July, so it will be a quick turn around for me to go to the class when I get back.

    Are you happy with the springs as far as the lbs.?

    9" Front Springs

    You could get them through Maurice, don't know if they can be bought direct.
    They are black powder coated. Maurice has the info on them.

    Thanks, Rick

    Tony - Yup, 550s on the front, and I'm very happy with them. I was getting way too much nose dive with the 450s, and now the car stays much flatter, particularly under threshold braking. The ride on the highway really seems about the same as it was back when I had 350s up front, so no problem there.

    Gary thanks.
    I am still interested in the 9" 550# springs.
    I was pretty happy with the way my Cobra handled with the spacers I have in the springs. Not much nose dive and took the turn pretty flat.
    It was a lot of fun.
    The street tires definately show there weekness under classroom Conditions.
    Six runs back to back. 15 runs total. 6-6-3. A great day.
    I am signing up for the level 2 class next.

    Smile Spring Change/Shock Adjustment

    Just finished installing 350# - 8" Hypercoil Springs in the rear. In the front I installed 400# - 9" provided by Pro Shock through Unique (chrome plated).
    Since I have Billstein Racing shocks I can change the Nitrogen Pre Load with a schrader valve. I am running 150 PSI in the rear shocks and 175 PSI in the front shocks. I have a high pressure inert gas regulator and tank for the nitrogen and a Billstein fill tool. While I was at it I deflated all tires and filled back with pure nitrogen. After getting the ride height set I did a test run up I-65 Saturday evening and back (40 miles total) running 65 - 85 MPH, then a few side roads and I like the combination. Good solid ride but not to harsh, really smooth at 75-85 MPH. I think you could up to 450 - 500# with a 9" spring. With the Pro Shock and it's design a 10" front spring will probably work well (they are black, powdercoated). With the 10" spring 400 - 450# should work real good.

    And Thanks for the info.

    Talking Mountain Roads

    Just the breakfast runs in the Smokey Mountains, one hell of a road course.
    Shades of the Past is coming soon, September the 7th through the 9th.

    What a difference stiffer springs make! The first photo is with 450 lb front springs in a trun at about 60 mph. The second is a similar turn with 550 lbs. up front. Much flatter and much more stable (particularly the inside rear wheel, which was bearly making contact with the lighter springs).

    Looks good Gary.

    I am thinking of ordering some 9" 650# springd from QA1.
    Having a Big Block I figured I would go up to the next spring.
    I Auto X this weekend at FedEx Field and had a blast. I ran my Good year slicks and they sucked. It was to cool and damp and sandy. I ran first heat and it was like driving on Ice. I should have switch to my street tires. I have the spacers in my springs right now and calculated at 525# with 7.5" of spring left. Alittle to short by Ricks specs for the spring hieght for our cars.
    It was still fun.

    Tony,

    Glad to hear you enjoyed the FedEx autocross! It can be very addictive, can't it? Hope to see you up in Cumberland one of these days.

    Nice to see that someone (QA1) has 9" springs. I may have to open the wallet one of these days.

    It is way more fun than drag racing and it is not as hard on the engine.

    I will make it up to Cumberland. Right now I am taking baby steps close to home.

    Found a website of pics posted from the Sept. 3 AutoX. I thought it was pretty cool to see the car and what it is doing on the course.

    Gary,

    I've been taking baby steps too, but decided to get in a different car. I still suck, but it is addicting.............

    Clay,

    Nice wheels!!! I'm envious. Way too much good stuff in your garage these days.

    As I'm sure you know, at the national level the Elises have waxed a lot of Vetts in SS. What a great car to use for getting into autox. The only concern I've heard from the ace Elise drivers is that there's only so much negative camber (I think it's camber) that can be achieved with the stock suspension. Not sure if that was just with the initial cars or if it continues on current production models. That said, it's a potent package for sure.

    How did you like the whole FedEx experience? I haven't done that yet, but I understand it's somewhat frenetic as they try to get all the cars through. But one of these days - - -

    Gary, you're right about the negative camber. The real pros, and there are plenty of them in this SCCA region here have removed shims and dialed it out somehow. Mine is still stock, but it has amazing grip, nonetheless. It's driver stinks, but that is a different story.

    9/3 at Fed Ex was my first time after going to an SCCA school. It is a bit frenetic, but it is extremely well-organized, almost like a symphony. Cars in each class park in pre-assigned grids within run groups and stewards direct you out at your assigned time.

    Gary, Clay is right. I beat his best time by 3 seconds in the Cobra with crappy tires.
    Sorry Clay. I couldn't resist.

    Uh, but not when I've learned the course, I might remind you............. We old guys need more reps to overcome the Alzheimer's.
