Hello, The front coil over's on the G-Body are pretty simple, just bolt in and go. We have rates from 250-650 and we would be glad to help you pick which rate is best. The higher rate can also not allow the car to go as low as some would like so you have to find the happy middle ground. For a non-auto car usually 450lb rate is nice and that usually allows the car to drop up to 3" from stock.
We offer two front end kit brands, QA1 and Viking. Both very similar. The QA1 is single adjustable when means the compression and rebound of the shock are adjusted together. The Viking's only come in double adjustable which is 19 settings for compression and 19 settings for rebound. You can make the shock autox capable, a nice cruiser or a drag shock just by changing the settings. Both kits bolt to factory or aftermarket lower a-arms with no modifications to the car.
QA1 Single Adj. Coil Over Kit
Viking Double Adj. Coil Over Kit
The rear kits include a little more bracketry and the UMI kit is almost ready for sale. We just did our final test run on them yesterday and we are very happy with our design and performance. Below is the lower brackets that bolt to the shock. We should have this kit ready in two weeks.
Please ask if you have any questions. thanks!
