I'm in on the GB for the 300# rear drop springs, I’m also in on the GB for the GC coil overs but I need to make a decision on the front spring rate.

I'm thinking of the 445# ones (they dont cost anything extra from the #350). I've herd that it's not wise to use the same rates for the front and the rear. I would imagine that I would want to keep roughly the same proportion of front to rear springs rates.

Anyone know what the stock spring rates are (roughly? or even the ratio)?

Any suggestions on a different spring from the list (I don't mind payn the extra $20 if I need a different spring rate?

Here are the options:

200
225 (+$20.00)
250
275 (+$20.00
300 (+$20.00)
325 (+$20.00)
350
375 (+$20.00)
400 (+$20.00)
445
450 (+$20.00)
500 (+$20.00)
525
545
600 (+$20.00)

i was gonna say 450-500, but 445 for no additional cost sounds good. i cant see 5lbs making much of a difference.

450 is what I use as well. Is a good match.

usually you want them to be about 100lbs difference larger being up front. so if you have 300 in the rear you would want 400-450 up front. i also will be doing the same combo with 300 rear and 450 GC's up front.

i should have also mentioned that if you are sticking with the 5m you may just want the 400# because the 450's will be quite stiff. if doing an engine swap to 7m or larger then 450+ is recommended due to the extra engine weight.
