Wanted to get some people's advice that may have more knowledge of lowering these vehicle's, will be lowering a 2013 Tahoe as soon as I round up all the parts and was wondering if it would be a good idea to start with new front coils since the backs will be new and I'll be using drop spindles and struts. You're supposed to use factory springs with them but the vehicle has over 200,000 so I thought it might be better to start with everything new and let it all settle together. Thanks, in advance...
