Hi there, Thanks very much for accepting me to the forum. I am just in the final throws of purchasing a stock 68 Charger 440 and am currently putting together my build sheet. I am still running through the finer details, but would like to have 500hp at the rear wheels and as much torque as early as possible right through the rev range. This has led me to look at suspension and I am slightly confused and would appreciate the benefit of your collective knowledge. I am looking at the following suspension packages: 1. Level 3 QA1 2. RMS Alterktion 3. Magnum Force Mopar Transformer K Member Conversion 4. Gerst GTS (Front and Back) I am new to this, however from my research the QA1 appears to be the best stock upgrade, while the other three are a more significant upgrade. Through reading many posts on this forum, I haven't seen great feedback on the RMS Alterktion kit; I've also read that although the Magnum Force is excellent, their service at purchase and post purchase is abysmal and there are no instructions for installation (other than a YouTube highlights clip), which is not great when living in NZ. I have read all positive reviews on the Gerst, however from my own point of view I can't figure out why it uses Mustang II spindles. I am leaning towards either the QA1 or the Gerst (provided I don't have to use Mustang II spindles). I would appreciate thoughts on the above and if there are any other suspension packages out there that I am unaware of. I would prefer a suspension package that is largely bolt in. Thanks in advance, Woodsy.
