BC BR coilovers
Possibly about to drop some money on a set of these to replace the standard suspension on an '08.
What are people's experiences with these, both fitting and use - I'm thinking about speccing 14Kg springs at the front and 10 at the rear.
After a softer ride with no track action predicted. Would 10kg front 8kg rear be too soft?
Can the ride height be adjusted high enough to look stock? (Previous car was so low even on highest setting and was totally impractical!)
Thanks for your advice/help!

What a good number of owners have done, myself included, was have FIGS (a vendor here on the forums) mate the BC coilovers with Swift springs at a rate of 16kg (front) and 12 (rear). This gives the very front heavy car some added stiffness. 14/10 is more than fine, but almost everyone I've come across with this set up has gone with the 16/12 combo.
Ride height can remain the same, though I would lower it slightly. The wheel gap becomes an eye sore when you look at it long enough.
Best of luck!

Actually my interest from KW has been moving into BCs simply because they cost half as much and the reviews I have been reading about them are pretty good. If the OP, MrFunex, hasn't seen this thread I would recommend you to look into it.

I agree with everything Bnizzle said. For the money, they can't be beat.
I had BCs on my first gen and I've got them on my F. I've got the Swift spring upgrade in the rates of 16/12. However, if I had to do it over I would've done the spring rates at 18/14 like Subiepunk has. They've got plenty of adjustability in both height and dampening so you can roll around at 4X4 stock height or slammed to the ground.
Good luck

So the people that have BC's the ride quality beats the stock suspension? Because I have a 2010 ISF and the suspension is pretty horrid. Or maybe I just live in a city with ****ty roads lmao.

Go 18/14. You won't have to set your coils as stiff but if you get lower spring rates then you might go all stiff and not be able to go any stiffer. I'm running Figs recommended settings 9 clicks front and 12 clicks rear. Rides fine to me, I feel like I could have gone stiffer.

I'm running the BC BR's with 14/10 Swift springs. 
Really pleased with them so far.
Softer over the bumps, drain grates, speed humps than stock. Mines an 08 so was pretty damn stiff before!
Having also installed the RR-Racing USRS, I'm glad I had the softer spring rates. The USRS has added a bit more stiffness to the ride, but not as much as it would have done with the 16/12 springs.
Also have the F Sport rear sway bar and Cusco front strut brace installed.
Very pleased with it on the different road surfaces. Just the track to try next.
I'd say go 14/10 to the op. Think it'll meet the criteria you gave us in your first post.
Cheers.

Thanks for the information. I should be getting my F sport sway bar and BC coilovers within the next 2 weeks as well. I will be keeping you guys posted

Thanks for the advice guys - I'm pretty sure I'll be going for the 14/10 with swift springs then!
Might be a nice Christmas present to myself!

Building on this thread here without starting another BC thread: https://www.clublexus.com/forums/is-...-or-not-3.html
What do you guys think about going with the 2013 OEM shock (Sachs) set-up with the swift springs for a lower drop mainly in the front??
I am split on the effectiveness of the BC coilover set-up from the feedback from the guys who have done the mod. If you read the link above it just shows some of the split opinions on them?
What springs rate to go with 14k/10k....16k/12k......18k/14k..... some guys think they're not worth it and if your going to do coil overs to go with Penske/Ohlins/KW V3 etc............
To go with what I said you have this link http://api.viglink.com/api/click?for...xt=Read%20this. here that Lance put up for consideration????
This quote from the link/article above stood out, does the BC come with dyno plots for each unit??
"Dyno Plots
You must, must, must have dyno plots for your shocks - and not just "typical" plots, but the actual performance of each of your shocks. Anybody who cannot or will not provide you with dyno plots for your shocks is a charlatan. Running the dyno was a huge eye-opener for not only what was out there, but also on what shocks actually did.
Not only that, but you need as a minimum plots of the forces at slower speeds, around the 3 in/sec peak speed range. Plots of faster speeds are OK, but once you're over about 10 in/sec you're into "big bumps" mode and you're probably just digressing the hell out of the forces anyway. You want to see the shock operating in low speeds, and that is where I found the majority of shock-to-shock variation lived. Shocks that produce near-identical forces at high speeds can be very different at low speeds - get the low speed plots!"
