• Failure to follow these rules may result in your threads being locked, deleted, or moved. Depending on the severity of your actions, or frequency of your actions, your user account could be suspended or banned. These rules are to help protect both buyer and seller.


    1. CONSOLIDATE all of your for sale items into ONE thread only. This means there will be NO making multiple sales threads for different items regardless if the parts are related or not.

    2. PRICE IS REQUIRED. We do not permit ads without an asking price for each item. "Best Offer" is not an allowable substitute for posting a price. You may ask for $1 but a price must be listed regardless. If a price is not listed with in the first 24 hours of making your sale thread IT WILL BE LOCKED or DELETED. Once a price is listed a bidding war is not permitted. If the seller gets an offer that meets his asking price, the seller should honor the asking price and sell for that amount.

    3. EBAY LINKS AND OTHER LINKS. We allow links to ebay ads, but you MUST have a buy-it-now price posted, or an asking price to stop the auction in your ad here (Not just in the link). If it is from another site or from here, do not use a link but post the full text instead with pictures if you have them listed. If a BIN price is not posted, then your thread will be DELETED.

    4. CITY / STATE are required info for each ad. Information must be posted in the first post of thread, NO EXCEPTIONS. Buyers and sellers reserve the rights to privately ask for full contact information on any purchase or sale. 24 hour notice will be given, if you do not comply your post will be DELETED.

    5. NO TWO PARTY SALES. This means no more "I'm selling for a friend" posts and will be deleted immediately with no notice. Seller assumes all responsibility of anything they post for sale.

    6. NO FEELER THREADS. You are either selling it or you aren’t selling it.

    7. POST COUNT AND/OR TIME LIMIT. We are requesting that you spend some time with us before you start a For Sale thread. A pre-determined minimum number of posts will be required or 1 year since creating the account + an intro thread (just so we know you aren’t the Prince of Africa). Any for sale thread posted out of the For Sale section to circumvent the rules will result in being deleted. Those who do meet the criteria and post outside the section will have their thread moved, constant violation of this will result in an infraction.

    8. NO BUMPING OR TT’ing YOUR THREAD MORE THAN ONCE IN 48 HOURS. Don’t worry your thread will still be a bold read until a user reads it and if people are really interested they will let you know. Post warning will be issued if in violation and on the 3rd warning, the thread will just be locked.

    9. NO THREAD DUMPING OR I DON’T LIKE YOUR PRICE. Don’t post in a person’s thread just to tell them they are too high, either move along and say nothing or throw an offer to them. The person can sell it at whatever price they think someone is willing to pay. Offenders will be issued a warning, if it is a constant issue then an infraction will be issued.

    10. KEEP YOUR THREAD UP TO DATE. This is really for your benefit, so you don’t get 10 PMs asking if you still have it when you already sold it.

    11. NO WEAPONS. As Admins we have determined that no weapons will be allowed to be sold, this includes knives, guns and anything else deemed a weapon (even if its a wall hanger only). We ask that if you want to sell these items you seek out the appropriate websites elsewhere to do so.

    12. Pictures are REQUIRED. Pictures of all items for sale. This is to help BOTH seller and buyer. As a seller it is MUCH easier to sell something if you have pictures of it. As a buyer you feel better seeing exactly what you are buying. Pictures should contain the item/s for sale and a sign of some kind that has your username on it. 24 hour notice will be given, if you do not comply your post will be DELETED.

    FRAUD & RISK. Buy and Sell at your own risk. Grand Prix Forums and its staff are not responsible if someone rips you off or doesn't send parts out in a timely manner. This classifieds section is a free service for the community, and it is YOUR responsibility to handle all transactions in a low-risk method. DO NOT contact us if there is a dispute between you and someone else, we are NOT INVOLVED. You can help minimize fraud risk by doing these suggestions:

    Pay using PAYPAL, using a credit card. This way, if a part does not arrive, you can do a charge back through your credit card company. If you gift it, then you have no recourse to get your money back when things fall through. Pay the 3% and have the buyer protection. Using someone else's paypal and gifting to pay for goods is violating Paypal's Terms of Service.



    Always ask for full name, residential address, phone numbers of both buyers and sellers. An honest seller should have no problem disclosing this info to you privately.


    Shipping things C.O.D. is risky. Try to use UPS or Fedex, so that you can track shipments. Have someone sign for it if it is expensive.


    Ask for references from other members, hopefully from other members who have been registered for longer than one year and are active here.


    Use your gut feeling. If something seems too good to be true, or a seller/buyer seems a little shady, don't take the risk.

    TIPS:
    -Post pictures: with mobile phones these days and auto uploads, it’s not even really hard anymore. Have it automatically drop in Photobucket, grab the Img tag link and paste it in.

    -Give good contact information if you aren’t going to be on here a lot.

    -If you are going to disappear for an extended time (vacation, time in jail, what have you), then give us a quick note that you aren’t going to be around. People will trust you a little more.

    -Look around and gauge your price with other items. Just cause you bought it for $1000, doesn’t mean it’s now worth $1,200 or even the original $1,000. You are free to ask what ever you want, but an item that is priced right will sell quicker.
  • The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

Possible new Hyperco Lowering spring kit



IT WS CRAZY......is the rate was 50# heaver, it woulda been a keeper. That pic is my rear coilover minus the threaded collar, and a 11"x250# rear spring that is mainly used on dirt late models
 
I calculated the Camaro springs to be a 2.25" drop, but forgot the were progressive, and I bet it was a 3" drop. Felt good for the 3 blocks I drove it like that, but the camber would have trashed my tires real quick lol
 
Hey guys, just an update.....I am going to personally buy a DNA kit and test them next week. If anyone out there has a good used kit from Eibach, Vogtland, B&G, H&R, etc and would like to donate them for about a week or two pm me. We will pick up the return shipping, just want a comparison of all the major kits out there before we make a final choice. I will post the results of all the testing with the rates, and cycle testing, etc. We will decide on what rates to go with at that point, and how much drop. We will do our best to make a kit that everyone will be happy with, but to keep costs down, we will only be making one type of kit. If we made more than one kit, the costs would go way up, since we would have to make lower qtys. And I know nobody wants to pay 250-300 for a kit is we can help it.
 


I want to make it happen.....it may take another month or so to get things finalized, but I talked with my GM and he is good with it. Thing is, we have to stock at least 50 kits to get the price point to where we want it, but I think we will carry them in our inventory once we make a final decision. We have never really done this, only stock private label stuff for our distributors, or other group buys when somebody purchases them, so it is taking a little research and development to make sure they will sell. We take pride in getting things right the first time, so bear with us guys, I am going to nake it happen. Oh, and Bio.....I have been thinking more about the "auto" adjustable coilover setup. I have some ideas churning through my head, but it will not be easy......we currently make a weight jacker for IRL cars that basically changes the preload on the spring at the touch of a button. I am thinking along the same lines for a coilover, but it has to be "dummied" down, because it would cost about 2k just for the parts for a street car.
 
So, if everyone will chime in, we will need to know a general consensus as to which rates and how much drop we are looking for. We all need to come to a consensus that will work for everybody. I personally was thinking a 1.5" drop all around with the front being 350-450 rate and the rear being 200-300 rate. This will be much more of a handling kit than a lowering kit.
 
I say something like an Eibach/B&G drop. I like the drop but if if wanted stiffer springs I'd have to go coilovers since the Eibachs are the stiffest, which I have. Most guys don't like a rough ride anyways so those rates are to stiff for most people.
 




no, we can do different drops for the front/rear......but only going to make 1 type front spring, and one type rear spring. What I meant was that we would not make 1 kit for 3" drop, and another for 2" drop, and another for 1" drop.
 
And the rates are based more for handling, almost like a "track day" type of kit. It should eliminate the need for the stupid bump stops, since the car won't roll as much. Also, we have to remember that the Bilstein HD's won't drop as much as stock type of KYB struts, so I am kind af basing this kit around the bilsteins, which I am partial to lol. Lifetime warranty+internal bumpstops+race proven technology=win in my book.
 
I have a 200# in the rear on my Bilsteins, and it seems really soft.......softer than stock. Makes the car feel like a RWD drag car when I take off hard.
