I'm gonna continue to be biased lol, but I guess it really depends on the aesthetic of the car too, I don't know how low Konis + lowering springs will take you, or even how low you want your car. If it's just a daily and you don't need it to be that low then struts + springs all the way.

As you probably know coils are gonna be a pain in the ass though, literally and figuratively. My experience with BC has been really good and I'd highly recommend BCs but the price difference is marginal, performance probably isn't significantly different either, and I generally prefer the look of BCs, and I got a very solid deal from Import Image Racing too. With that said the ride is decent, I got 8k front 6k rear spring rates, and I think I should've gotten Swift springs, would make for a slightly less harsh ride over bumpy roads and probably closer to advertised spring rates. The ride isn't super bad but it can get pretty rough if the road sucks. I could lower the damping a little more and get a more comfortable ride but I have it currently set to where I get the performance I want and the ride that I can live with.

They handle pretty well the way I have them set up, even with my balloon tires giving me body roll, but once I get new wheels and lower profile tires the ride is probably gonna get significantly more harsh. The handling difference was obviously night and day against the stock struts. Just giving you my 2 cents about my relatively short experience with coilovers.

I agree with dodik's idea of just getting some "inbetween" suspension, it can also help you figure out which direction you want to go with suspension. Maybe struts and springs won't give you the right look, or maybe you really like a smoother ride and coilovers will just make you uncomfortable while driving. Or maybe you won't even want to do the conversion later on.

Also yeah, I love Regamasters too!

P.S. my mom actually prefers the ride with coilovers vs when I had stock suspension lol, and she also likes that they make me drive slower, except in the corners, then I haul ass! So in my case the BC coils got the mom seal of approval!
