placed the order.

i'm curious to the ones that have this setup? how is the ride overall on city streets? is it really harsh? I've heard a couple say it's not too bad then i'll read a review stating it's miserable. I'm not one of those, don't want to mess the ride up guys. I'm fine firming up but I don't really want to make it annoying and overly harsh.

The rear 350s are rate of 800 where the SP082s are 740. The 082s might be the ticket, especially for a EB car.

one review:

I don't think any of the aftermarket stuff is made for comfort...if anything, it compromises a tad of comfort for significant increases in handling. At best, the comfort level will be equivalent to factory.

The more you go racecar-ish, the less comfortable will it be for street.

In theory, for a EB you could get away with lesser rates since the car weighs less...but not much less than a GT.

one other thought... sway bars

does anyone know what the differences are in regards to stiffness or diameter with the following bars:

Performance Pack
Track Pack (37mm front / 25.4mm rear)
GT350 and R

PP, and GT350 to my knowledge, have the same bars.

32mm Front
22.2mm Rear

Now there may be some wall thickness differences....not sure on that.

914 lb/in, not 800. BMR SP088's are 800 lb/in.

not sure how i missed that.... i remember seeing the number now that you showed me. BMR Handling by comparison is 980, so a compromise between the Perf and the Handling maybe

Pic of my setup...GT350R fronts with BMR SP085 rears.

To the best of my measuring ability, it rakes about 0.8 degrees...does it need more rake?

Perfect!

No. Leave it alone.

That is a handling machine right there. Bet!

They're all linear. The 350TP has a little softer damping, softer front springs and rides about 0.5" higher than the R.

Untrue, springs have been tested the regular gt350 rear springs are more progressive.

GT350r is almost an entirely linear spring.

I can post graphs if you don't believe me

I believe [MENTION=26233]Rebellion[/MENTION] is trying them out. GT350R springs lower ~20 mm. The GT350 left rear is the S suffix.

I personally am looking at GT350R fronts unless [MENTION=9985]BMR Tech[/MENTION] comes out with some min drop springs with Handling spring rates.

I'm seeing mention of FR3Z-5560-T in the beginning of the post as the "R" spring, then I also see mention of the FR3Z-5560-S as a 350 spring. Is one the R and the other the std350 or are they fully interchangeable as the left rear spring.

Reason I ask... I ordered FR3Z-5560-S x 2
