Has anyone ran the eibach drag launch kit with Lakewood 90/10's and 50/50's? How was the ride quality, I've read some complaints that it's a very hard ride.
Not sure what the rates on the rear springs are, but I ran moroso trick drag springs for a period of time as well as 4cyl springs (front only) and it was incredibly soft in the front, my koni's are adjustable and I've been told on soft they are 70/30. Ride quality was good IMO, bouncy, but far from hard.
Handling on the other hand couldn't have been any worse. But judging by your signature that doesn't sound like your thing.
I'd assume the eibach drag kit is similar to the moroso trick setup and even the 4cyl springs.
I ran them in a car about 15-20 years ago with the airbag in the passenger rear. They are not that bad but the 90/10 is going to be sketchy if you do a lot of DD.
