First ...Welcome to LS1 Tech. Second I just wanted to throw this out there for you that UMI Performance also offers a wide variety of suspension parts that may meet your needs. Below is a link to show you what all we have to offer! The only problem is there is two different types of racing and two different suspension set ups. Road Race guys lower the vehicle and go with full length adjustable torque arms. And Drag Racing guys go with Coil Overs to help with weight transfer and shorter torque arms. http://www.umiperformance.com/catalo...tmr1mfgsjjgng1
