So I see 600 and 800 series steering boxes offering 12.7:1 ratios. I have no clue what our stock GN has. Currently I have Spohn upper/lower fronts and rears/Spohn F/R pro Tour sways/bilstein shocks. I'd love to quicken up the steering box but I know so little about them. Anyone with first hand experience? What are the CON's using the smaller, lighter version. Some offer both versions. Prices very from $500ish range to near $900ish range. Thanks for any "real world" advice.
