Pro Touring 10K

I believe they are as settled as there are going to get. They where on another car before mine. And run in autocross events. So yes they have been cycled. I'm aware that there will be weight added to the car. Gas tank glass interior just to name a few. The free arch height is 5" its dropped about 1/2 an inch in the pictures. I can add about 300lbs in the trunk and it drops about an inch and a half more but that's really not quite enough. I will talk to Flex form on Monday to get there thoughts. I'm having spring built so I'm hoping we can get where I want with the springs. If not I will notch the rail to set the spring up in the rail 1" and adjust from there. I know Flex Form can do a 4" free arch. I'm hoping they can do a 3 1/2
