87 firebird formula 350 heavily modded/custom
dropping the bird with ebaich sportline springs, 1.6" front and 1.3" rear
i was told that i couldnt use the stock springs with such a drastic shock, so i was gona go with KYB AGX adjustables but i havent heard too many good things about them, so now i think im gona go with Tokico blue HP shocks at all 4 corners...and at 290 for 4 im not complaining lol. just wanted to hear wat everyone had to say and what there happy with. gona be ordering soon so any quick info would be appreciated.

also ran true 3" duals that dumps before rear axle and i have horrible ground clearance where the trans crossmember is located, prob alil more than 1 inch and now that im dropping this 1.6" im gona have to do something about this....3" pipe is running from headman longtubes. has anyone conqured this ridiculous obstacle without removing the subframes? ive also done mild steel 2"square tubing subframes from the front subframe that go straight back to the rear subframes that have been notched and fully welded thro the floor. im looking for a clean setup so pics would def be appreciated

Well as for the shock selection, I am running AGX's w/ my Sportlines right now with no complaints. Be ready for a pretty rough ride and avoid potholes and dips in the road at all costs.

As for the exhaust...good luck, my stock dual-cat setup sometimes has trouble dragging on speedbumps haha
