I have Bilstein Heavy Duty shocks on the front of my 88 6. I run Boge turbo gas in the rear. I personally feel that the bilstein's in the front will save me money in the long run. Being that these cars are so heavy the Bilsteins take some of the stress off the front end components that we all know can be troublesome. I like the ride a lot. Both are good but I think the Bilsteins are worth the extra $$.
