Lowering springs 01 droptop

[Brewkett]

Looking to lower the car, 01 convertible with IRS.
Eibach specs springs for the 99-01 and 03-04, coupe and convertible using the same spring.
H&R Specs coupe and convertible with different springs , but uses the same spring for all 99-04 cars.
How can the 99-01 get the same drop as the 03-04 cars if the 03-04 cars weight more using the H&R springs?

I also know the convertible weighs more than the coupes but not by much.

What spring should I use to get the 1.5" drop?

The convertible is 300lbs heavier.

I used the Eibach Pro-Kit on my 01 vert. Dropped it 1.4 front and 1.5 rear.

Car really could still do with another 1/2” front and back honestly. It didn’t make much of a difference visually.

Personally i like using the 03/04 cobra eibach prokit. Sits real nice on all 99-04 mustangs with an irs added.
