If I had to pick between the two, I'd probably go GC. You've actually got a couple more options too. You can follow the DIY thread on making your own coil overs or you can get the Held kit. Personally, I went w/ the Held kit with 325lb springs to accommodate the extra weight of the engine when the swap was done. I'm happy with the results.

No to WCF coil overs as there springs r to short and they sit on top of the spring perch. I had a set of the WCF coilovers and sold them cause I was not happy with them at all. I would do the DIY coilovers thst way u know what u get.

I did a quick search for held kit and didnt find it. Please provide more info.
I recall another IMSA ? , user posting pics, about his Ground Control kit, trying to get them to work, that was after I had ordered a coil over kit, they sent me one sleeve that was cut in half, a six inch Eibach spring, ? WTF ? I didn't even bother attempting to install it because, It would unseat and flop around, I called them, John, this is a few years ago, he just gave me the runaround, said that because I never installed them, that how could I possibly know if they wouldn't work ? I gave up. The only time I have ever had a problem with all the purchases I've made over several years and it was with Ground Control.
The best coilovers are the ones you build yourself.
The ebay kits are crap, springs are way too short. As for the kits with the sleeves and adjusters, they will probably work alright but are short so not a lot of room to play with springs.
I personally went with A1 racing adjusters and AFCO racing springs. QA1 makes good springs as well, I built mine for less than $150 including struts.
Take care to be sure the adjuster sleeves have the same ID as the OD of your strut, and make sure the ID of the spring is just a tiny bit larger than the sleeve for the adjuster, you want it centered on the adjustment ring.
These are the ones I was planning to buy. I'm doing an '88 cradle install in my '85 so I need the upper relocation brackets too. I have Koni's to use with them. Does anyone have any experience with these coilover kits?

The Koni North America 2012 Motorsports Catologue lists the coil over parts in the PDF document on page #31. 50mm inner diameter sleeve's etc. http://www.koni-na.com/cat_search_form.cfm I haven't ordered them but planning to.
I have Koni's with 10" 400lb spring going on the back of my coupe. I will be putting my old WCF kit on the back of my 88 GT but I plan to modify them by cutting off the spring perch and using a 10" spring vice the 7" spring that came with the kit. The top hat is a decent design but all of the options are about the same. Best advice I have is get the best one the first time, it cost too much to upgrade later, pay a little more now to get the kit you want. I have spent so much money over the last few years getting what I could afford at the time, and then upgrading later, in the end you spend so much more doing that.
Thanks for sending the link. These look pretty good but on their website I don't see these called the "Held Kit" . Am I missing something? How stiff is the 325 spring compared to stock- does it feel a lot rougher?
Thanks!

I just orderd springs, sleeves, adjusting nuts and a spanner for $150.00 from summit for the rear of my Fiero. The sleeves were back ordered and should be here Tuesday. I will be waiting for some warm weather before I get out in my unheated garage to install them. I went with 275# springs. I am doing the DIY method and will be modifing my factory struts. I installed the struts last fall so they are still like new.

Do you have part numbers for the Summit springs, sleeves, adjusting nuts and spanner?
Thanks.

I have an '87 with an '88 cradle, the Arraut relocation kit, Koni Reds ("Specials"), and 300lb springs. It's good, but not anywhere near top of the line in terms of suspension. I can't tell (aka, haven't put in the effort) as to whether the springs are not enough (3.4pr back there) or the Konis are not enough to control the springs, but the back end is far bouncier than I'd like. Once it takes a set it's nicely controlled, but going into compression is a little rough. IIRC I have the shocks are their stiffest setting, it's possible backing them off would help, or maybe a stiffer spring. There's definitely a mismatch there.
That said, I don't think you can do any better than this for reasonable money. You could get into high-end struts for a grand and make big improvements. but that isn't a step I'm willing to take. So, while I'm not thrilled with the results, the dollar erformance ratio is a-ok by me. Chances are I wouldn't do anything differently if I had to do it again, though I *might* go for a stiffer spring. 300# seems aimed squarely at daily driver and not performance as the ride on normal roads is softer than my XJR. Heh.
