i think you might be asking in the wrong
plaice mate... this forum is more about the lighter side of bus ownership
if you've got your bus booked in at T2D, and you're having their new spindles, and i can reasonably assume you're buying a beam off them, then the plain truth of the matter is that nobody over here at least is gonna give you better advice about lowered buses than medhurst 8)
i mean, any advice you get from here or the likes of VZi is only ever gonna be based on an individual's experience, usually from one installation, and say you get somebody fitting one and they say the ride was ****, but unbeknown to them the tracking was set wrong or there was a trailing arm binding in a bearing or any one of literally dozens of things that might not have been 'set up' properly, then where's the 'control' element ?
take a look at T2D's blogs and you'll see that they're laying stuff out every day of the week, lowered, narrowed, slammed, it's all going on up in da house burwell what's up... peace...
sorry, erm, i'm just saying that they do the stuff on a day to day to day basis, and if you said to paul, "i want my bus to look like... THAT (insert photo) but i want it to ride like THIS" (do wavy thing with your hands or whatever) then he'll be able to fit you up and you'll know it's gonna be dope, rather than relying on subjectivity.
*lord low* up in da house one more time... peeeeeeace
