Going to an adjustable shock would allow more room for tampering. The biggest problem with 600Racing is that they are a business and have contracts with specific companies so when those contracts come to an end it could go one of two ways. Either the company would renew their contract and continue doing business with 600Racing as a supplier for shocks,tires,wheels, and so on or they will not resign leaving 600Racing no other option than to find someone else to fill the now empty spot. This is a problem with trying to run a 100% spec division and every so many years you will have things like this. You can't control things like this so you kinda half to just roll with it.
As far as a spec division this is affordable no matter how much you spend because a crate modified or a crate late model is a "spec" division. The only thing that is "spec" in those divisons are the engines, the chassis along with all the components are they same as the Small or Big Block divisions. You may have a spec tire as well with an extra option for a compound but you will still be spending more money on shocks, springs, torsion bars, birdcages, and i could continue with a list a mile long with options and how deep your wallet could get for those spec divisions.
Think about this, although at this current time it may hurt our wallets with the tire change, a possibly shock change, and this inhouse engine program that i dislike but in the long run everything will be the same with every car and you will know what everyone is running. In a "spec" crate division the only thing you have the same is engine and tires but outside of that you will always be searching for what is better. Are you getting beat due to the driver or are they running a torsion rear end compared to your coil over rear end, are they running five wide hubs, are they running 5 degree spindles instead of 8 degree spindles, what type of compression/rebound ratio are they running on their shocks, are they running a normal steering box or quick steer box, what degree spoiler are they using. I could go on forever with this list so when it comes to having a spec division and rules this division is truely one of the cheapest. But it still could get expensive if you have some bad luck but that is racing which sucks no matter who you are.
The only thing this division is missing to make it great is control, we have several greats tours and promoters but that overall control from the top is a little lacking which then it trickles down hill it gets bigger until it hits us as the individual. And because of this control problem it hurts us with the total purse we run for, the more we give up on purse we will never get back. Legends shouldnt be racing for $150 to win or heck $300 to win is even low, we should be racing for $500 to win weekly but when tracks see the lack of control and bullcrap that goes on they dont want to pay because it does nothing but annoy the people in the stands. When people are booing is looks bad and make promoters think twice about what their paying and those things they boo about could easily be fixed with the use of a black flag and enforcing rules.
So overall in my opinion 600 Racing/Inex has a lot of good things going for them but could still be better in all areas but i think as a spec division they do a good job trying to keep everything equal and fair so no one could out pay their competition.
