SpeedTech Subframe

[XLexusTech]

I but the mandatory extras may add up to more than I want to invest.

Dont forget the few Hundred to ship it (You pay this for any sub)
It adds up fast. That is why this sub IMHO is tough to swallow as the end cost of the ST gets close to no equal to Subs that offer better Geometry things like front steer and direct fit LS motor options AC clearance and so on.
The market for this sub is clearly targeted to those who are already commited by buying contol arms for example.
I think thier is a fairly strong market for slightly used or basically just bolted on part. (the parts are easy to sell with littel loss maybe a 5-10%)

I would take that hit all day long instead of allowing the ownership of those parts drive my Subframe choice.
