Coilovers??/ performance

Where can i get coilovers for my e28 its a 1988 535is. Im not looking for the best of the best just the poor guy ones haha. Also what is a good performance chip to buy for it since it has 3 inch exhaust, cold air, and 24lb injectors. What are some cheap things to get more power.

Not many choices for coilovers. The best of the best is ground control. But packages start at $1,700. There are some on eBay for around $1,000. Nex? And maybe xyz? All require cutting of the strut tube and such. As for power mods check out a chip. Turner Motorsport makes a decent one. Around 250. But you can find used ones a lot. Check out mye28.com for some used ones
