Even cheaper at FCP as they come down to $925-930 after the discount code. And honestly, with FCP's warranty terms and customer service, I'd still pay them the little extra bit I'm not complaining about my win-winYou can get the BC's on Amazon for $995 + free shipping and get them in 2 days if you have Amazon Prime. May be able to find a slightly better deal on eBay also.

Swift springs are what BC Racing sent to Viron and I for replacements.You're going to want to run ~550 lbs front and rear for mixed road/race, ~800 lbs front/rear for mostly race. That is, if you can choose your spring rate. Eibach and Swift make the best springs out there.
I'll let him speak on the calculations he made to come to those #'s. I'm just glad that I won't have the front crashing about like it does nowSo interesting to see this, cause on my G35 I had 12k fronts and 10k rears. There was a larger following of BC and I felt like my car handled on rails when I had them on there.
I'd be interested to see what a true suspension guru would spec for our cars. With the weight distribution being so far forward, I would think the fronts would want a stiffer springrate, something like 12k fronts/8k rears.
Edit: After comparing the cars, the dry weight is about ~250 lbs more, and the distribution is 1% more forward. I'd go with 12k fronts and 10k rears just like on my G35 and use the valving to adjust for the additional weight up front and rear. There are 30 settings to choose from lol.
RBitBug's coilovers will be $2k+, BC's are $900-1000 and $100 to rebuild if any break and they are SOLID coilovers for non-pro use. If I didnt have brand new 4C on my car, I'd replace them with BC coilovers. In fact I might sell my 4C just to get them...
What did you do about the 4c system to disable it or do you just have to deal with the lights on the dash?To answer your question, the current BC configuration is 5kg front, 12kg rear. Another member discovered front was too light and causing the shock to be compressed where we were nearly riding on the bumpstops so he contacted BC and got a set of 8's for the front. After testing, he feels 8's cured much of the crashing but might be a little extra. I went with 7's per his suggestion and will be installing them this weekend. Will post a review next week.
Buy through FCPeuro, as they have a promotional code of $75 off for any order $999 or more. They also have lifetime warranty and great customer service In your order, let them know you would like 7kg front, 12kg rear...just wait a week or so till I write my review.
For a street car and average track duty, BC is more than enough and by far the most cost-effective. It's cured the nasty sidehop that I had with 4C and once this issue is resolved this weekend, I think I'll be more than happy with my purchase
4C resistors fabbed up in sweet little boxes by Viron This is a solution for 04's, whereas 05+ simply require cutting the bottom half of the shock out.
