    Hey Gentleman, I thing I read a post that talks about changing out shocks. I have 2 that are leaking. Kit includes shocks and something that keeps the light that does the active stability from coming on.Thanks

    great info, but i will mention two things about the spring pads grand daddy listed at the end of his post.
    A. they are not integral to changing the shocks themselves, but might as well do them while you have everything opened up.
    B. the pads he listed are lowering pads, many have used them, but they might be stiffer, might need more adjustment to get height same as before, or maybe you want to go lower...
    Fireduck69 recently found an oem style pad that is thicker, thus not lowered, maybe not as stiff.
    here they are:
    97-19 Stock Spring Adjuster Bolt Stop Pad 97-19 Front 05-19 Rear | Corvette Central

    hey grand daddy, did you do a thread on your recent upgrade? did you do it yourself or have a shop take care of it? i'm outside philly, if there's a competent shop that did your xlr, i could come over for a similar upgrade!

    I have a Chevrolet Dealer (Renn Kirby) in the Gettysburg area that has a Cadillac XLR mechanic that knows our cars, heís done everything I ever had done at the dealership. Their hourly rate is $105 an hour. I bought a 4 set of Lowering Bolts Spring Adjusters from Cubby and threads was the wrong size, so I called him, he told me where he bought them (Southern Car Parts) and returned the wrong size back to Cubby! Mean while I had the dealer get the thread size M 13x2.0x50M called Southern Car Auto Parts and had them shipped out overnight, but still took days, but then I get a call from the dealer that there was only 3 of bolts in the box! So anyways everything got done and I was back in business in about 10 days! The car rides about the same, maybe a little stiffer, but definitely handles better then before! Iím satisfied at about a 1/3 of cost of the OEM Magnetic Shocks

    Keep in mind, my XLR is a 2005 base model. Fireduckís I believe is 2007 XLR-V and I believe the Lowering Bolt are different size, and all 4 of mine was the same size.

    I originally replaced the spring pad bolts with the lowering ones. you have to raise them about 1/2 inch to bring the car back to stock length .that puts extra pressure on the spring and does make the ride a little harder. If you lower the m1/2 inch the ride remains about the same but you get clearance issues with the front radiator lower support. I like the original even if you wan to lower the car. this is a rubber to metal contact so a little lube helps prevent wear and noise. I have swapped around vette and xlr springs but never ran into a size difference on the bolts. All of them seem to have been the same. Maybe just lucky.

    Side note. You need to take the time to check the lower radiator supports. On almost every car I look at, at least one of the four mounts is broken. Most have two broke. when it gets to three ,you risk the radiator assembly dropping down and the support doubling up which will case major damage. Before that happens it can be removed and welded ( aluminum) and reinforced a bit .

    Good question, Benny. Interested in finding out myself as I might be forced to do the shock swap if they [G7 Computers] can't get my SC module up and running. I just bought a Tech 2, but still need to do some research on usage. When it comes to 'computer stuff' I know just enough to screw it up royally!

    I had the dealer do my exchange, the mechanic is on vacation, that worked on mine, Iíll try and call next week and see if heís back from vacation and ask if he did something for that, if he had a situation too. I think I recalled someone else had that, and found the simulators, may not of been in correct or in tight, so you may want to check that too if you havenít already!

    you really should not have to do anything but maybe reset he battery and drive it .A couple of the sims do not snap in and have to be zip tied together so make sure the yare good and tight and there are two different ones wit ha 2 wire and a 3 I think so they are not interchangeable. I have heard they do not work on some cars but I thought that was the early 04 corvette

    Good Morning, I did hear back from Casper electronics, they said to drive the car for a few cycles to relearn the computer. They said the parts were made foe the corvette but to let them know if it works for the Cadillac. Will post if it works. Thanks
