Post Koni Inserts & GC Sleeves Vs. BC BR Coilovers

I've been researching a suspension overhaul for my 02 WRX wagon, and I've narrowed my choices down to ~2 choices. My driving is roughly 80/20 street/track, and it's my DD. I want to drop the car about 1.5", and damping adjustment would be sweet. My budget is around 1500, but I can swing a few extra hundred if its really worth it. Also, I plan to do all the work with the help of a few friends.

Currently I have the stock wheels with winter tires, but I plan on snagging a set of 17" or 18" with performance tires for my summer set.

1) Koni Inserts ($650 shipped) with Ground Control Coilover Sleeves ($400+ shipping)
+ Group N Tophats- front and rear ~$400+shipping
+ Donor strut housings (<$50 hopefully)
=~$1600 total

I've read that with lowering Konis, bump travel becomes an issue. Ground control makes a coilover kit for $2000 (), with shorter koni struts to allow for more travel.

What year donor struts can I use if I decide to do this route? Does it depend on which tophat/camber plate I use? (anyone with a set of fried struts that'll fit- please PM me!)

Would running the inserts require also running camber plates to account for any change in geometry when I drop the car? Or would camber bolts suffice? (i've read it's unsafe to race with these...)

Can anyone with personal experience with Konis speak for their lifetime warranty? How easy are they to work with? From what it sounds like I'd need to have these installed professionally in order to keep the warranty .

2) BC BR coilovers (~$1000 shipped) (includes front camber plates)
+Rear camber plates? (~$165 +shipping), or just camber bolts
= ~$1200

Would I need rear camber plates with a 1.5" drop?

This option seems a little more appealing (less work and cash), but I have concerns over the quality. Can anyone that's used these speak to their quality/warranty? I know they have a 1 yr, and its 95 per coilover to replace them after that . But If they're prone to a rebuild every six months then I'd rather go with something more reliable. (I've read through the 75 page post of how awesome these are, but I'd like to ask for thoughts from those that have used them and had a poor experience)

Anyone that's used both of these setups (or something close) would offer invaluable insight!

i paid 550 for koni's ask for some deals from the nasioc vendors here.

i wrote up a little thing about my setup about 10 threads down or so if you want to check it out i am so happy with my setup i would recommend that. Although i am a '12 but the ride would be similar quality.

i would stick away from bc racing, most coilovers made in the 1,000 catagory are all the same thing from asia with different logos on them. I would go for quality, i was considering h&r or kw variant 1 for my car, hr dampers are made by bilstein. both dont have chamber plates but since you do most DD driving it shouldnt be an issue.

and speaking for your budget i paid 550 for koni's, 350 for rce yellows, and like 500 for sway bars front rear and both sets of end links. so that is under budget for good quality parts.

as per your install i cut up donor struts and did that work in about 15 minutes. Had my brother install them bc i didnt have a weekend to do it took him about 3-4 hours with good tools and wall mounted spring compressor.

A daily driver with coilovers in Chicago winters! Ouch!
I would not recommend that unless you like seized parts.

If you are not using your wagon strut tubes I would go with Whiteline Com-C front tops and or slotting the struts to get some negative camber back or more if you wanted.
I am not a fan of aftermarket camber bolts.

If you are tight with money you can go with stock rear tops. Most people do not feel that much difference in the rear with Group N compared to stock. The fronts are a different story though.

Skip Group N tophats. Either stick with stock, Whiteline Com C or get some plates.

I would go with the Koni setup 100/100 times. Better dampers, better quality springs.

I would have to disagree in regards to front Group-N top hats. They do make a huge difference compared to stock. Front stock is way too soft.

This is not so with the rears. Although soft too, it's just not as noticeable. Unless you are into auto-x or track days, the rears are not as important.

Edit: If you need the extra negative camber you can go with Whiteline Com-C. Same hardness as Group-N.

Subidude81, i took a look at your other threads and noticed you also ran tokico spec ds. I was considering these at one point, but I'd be interested in your experience. I know it was on your 2.5i, and the bcs were on your legacy, but can you comment on build quality differences, and ease of use for each of the two setups? Any issues with either? What mileage have you put on them?
