What I have found is.. they do get softer.. but they also lose alot of forward bite... the top guys in my area change them about every 5 races... sounds stupid but I tried it once, and if I had the money I would change them as much as possible..Pig

When leafs wear out, they don't really loose their rate, they loose their arch and ability to hold the car at the ride hieght they could when new, but more importantly, they loose their ability to resist the 'wrap up' that occurs under acceleration. Fresh springs can hold their shape better and give good forward bite, where worn springs are likely to 'wrap up' or turn into a 'S' shape from the traction of the tires.

Would I gain anything by putting the stock springs back under it?

The lighter your spring rates are the more likely it is that they have exceeded their yeild limit too often (150 lb. rears might barely make it through a season while 225 pounders might be good for 2 or 3 seasons). Most of your front runners replace them at least once a year (a pair of their throw-aways may be better than what you have). I wouldn't reccommend putting on the original springs. Summit has a great price on Landrums, they usually show up in 1 or 2 days and shipping & handling is $16.95 for a pair (normally they charge $6.95 for your whole order, but some big items like springs get a $5.00 surcharge). If you are interested, a crude way of checking leafs is to turn one upside down and get a haevy buddy to stand on it then compare the change in arch to a new spring.
Good Luck

Has anyone tried the springs that speedway makes? They are a little cheaper than the Landrums. Are they just as good? I looked in the summit catalog and they didn't have the right ones.
What would happen if I put the stock springs back under it?

CALL SUMMIT. In stock, they have (I'm assuming this is for a Dirt Camaro) 175, 200 and 225 lb. springs (only 2 left of the 225's , so hurry) and can have in 12 days 150, 212 and 250 lb. springs. All springs $89.95 each except the 250 lb. is $100.
Haven't EVER been impressed with Speedway's house brand stuff (MOSTLY JUNK), but their name brand stuff is often a good deal.
