Are LS1 stock springs any different than LT1 stock springs?
Need to pick up a set of stock springs for my 93 Trans-Am. A guy locally has a set from an LS1 car. Are these the same as the LT1 stock springs or should I hold out for a set from an LT1? These will be going on a set of Koni Yellow shocks on the lower perch in the front.

Park an LS1 on stock springs next to an LT1 with stock springs and you'll see what I mean.
And before those who weren't even old enough to drive back then come running in here throwing around internet "facts" they've encountered..... I bought my car new and it didn't have many miles on it when the 4x4 LS1 cars came out. There is a big difference in ride heights between the two cars.

If there is a difference in rate, the more likely explanation is that LS1 springs are taller than LT1s.

Here's another thing we noticed as well. Both of our Z28's were nearly "identically" equipped, yet when we corner and cross weighted them, they nearly weighed the same (only about 10 lbs. difference with concerns to front end weight).

But I do agree the springs are probably taller on LS1 cars.

More weight generally does require higher springs rates for an expected performance, however what people don't realise is that the stated weight savings of the LS1 is only relevant to the LS1 itself, not necessarily the whole front end.
Even Sam mentioned something similar to what I've stated, which is pretty much why he criticises Eibach's rationale for their vastly different spring rate designs between LT1 and LS1, whilst he simply sticks to either V8 4th Gen F-bodies for his rates.

If there really is a difference in rates, I doubt someone is going to feel that 18 lb / inch difference.
I was trying to say that if the LS1 springs feel softer to someone, it is probably because they are taller and therefore have more travel.

wow... that's nice....
