Yeah that is correct for BOTH**
There a Poll we have. Go on there an Vote please..
The more votes there is the more the companies see that there is interest for Spring, Coilovers for the RC_F.
I will be sending them the link with the Poll showing that there is interest so that they cant start the process quicker..

Thanks for the update bro! Curious to know if there is a difference in the rear suspension between a Non-TVD vs a TVD RCF... Anyone else going to go this route and lower their F with IS350 BCs???

Damn you are quick !! I am impressed . Looks great, but with a car of this level I would have waited for a dedicated setup engineered for the weight of the car, especially with that V8 up front relative to the V6 in the IS. Did you consider a higher end product made for the ISF? Do you do any track time? or intend to ?

Thanks, my original plan was to make this temporary until an official setup comes out but ive been so pleased with the ride quality results that I see no need to change.
2nd gen ISF suspension setup is not compatible with RC.

1.25" lower in front
1.5" lower in rear
This is a work in progress using coil overs but I am still currently running stock dampeners in the rear. This weekend I will finish and have adjustable dampeners in the rear and THEN I will do the alignment. I was waiting to finish this weekend and then I can share my results with everyone... right now because I have aftermarkets (adjustable) struts in the front and stock in the rear, its difficult to comment on ride quality but so far everything has worked out great. I was able to dial the ride height exactly where I wanted and the ride quality even in it's current state is more than acceptable.
UPDATE:
Good morning gents, sorry for the delay with the progress posts but I'm happy to report everything is complete with the suspension and I couldn't be happier. Delays had nothing to do with complexity of install, I've just had such a busy work schedule it's been tough to log in and update everyone.
I am running the BC Racing BR series Coilovers for the 14+ IS350 ... they bolt right up with very minor modification. on the rear struts, at the bottom where it mounts to the car, BC supplies two machined spacers that fit into each end of the eyelet of the bottom bushing. this allows them to use a common strut across multiple applications and these spacers (shown below in pic) are used to make the width of the bottom mount match the OE strut. In the case of the IS350, the bushing/mount is wider than the RC-F so you have to machine these spacers down about 5mm each in order to make it match the bottom mounting width of the RC-F strut. no modifications to the car or the struts themselves, only these adapters.
I have my struts set to the softest setting and the ride quality is excellent. easily matches stock if not better. It's still a sports car with sports car suspension but it rides so much better than the GT-R (in comfort mode) or the M3 (e92) ever did.

There is no camber adjust front or rear so I was expecting problems. However, everything actually lined back up within factory range. Albeit the lower end of the range but definately acceptable

Vorshlag camber plates should do the trick for you. I don't see that they offer them for our cars, but they are a custom fabrication shop. You might try and see if they plan on offering some for it in the future if you're concerned. Drop looks great though =)
