Relentless Autosports Coilover package...

Kirkster

I ordered a set of BC ER coilovers from Scott in mid november and they are on the UPS truck "OUT FOR DELIVERY"...

After a lot of consideration I decided to go with Scott's coilover package. Which consists of the BC ER Coilovers, re-valve of the shock, and 10K/12K swift springs...

I will post up some pics when they finally arrive today... I may get the install done this weekend if the weather does not turn into utter crap...

Isn't Relentless somehow tied together with VRT? Which scammed a bunch of people in the Z community?

Kirkster

I poked around a bit and only saw that Scott at Relentless had fixed some of the VRT problems...

Scott @ RA

^^ This is a prime example of the rumor spreading problem This subject has been beaten to death time and time again...
Please, if you do not know the facts first hand, please do not spread the BS rumors you read somewhere and become part of the problem. Thanks.

Thanks. I have had WAY more than my fair share of unwarranted blame from that company, that all was ironically and strategically put out there in the rumor mill by other competing shops.... and Yes, we have fixed several botched cars, from VRT back in the day as well as other more (supposedly) reputable shops currently. My short stint as a subcontractor at VRT ended with me leaving due to me finding out about shady practices there... almost a year later (in 2007) and while vrt was still around scamming people, I opened Relentless Autosports. Relentless Autosports had, and still never had anothing to do with vrt.

Scott @ RA

Glad you got the coilovers, Kirkster. Sorry for the delay (damn SEMA LOL) Hope to see pics and a follow up review when weather permits...

Raven

what are the regular spring rates of the ER's?

ChrisSlicks

That is the regular spring rate of the ER, 12K front, 10K rear.

Why are the shocks re-valved if it comes with the spring rates that the shocks were designed for?

In this particular case I have no idea, Scott will have to answer that one. It's not an uncommon practice, even at stock spring rates people often find they don't have enough adjustment at one end of the range for certain types of driving.

I quoted your post as reference to the standard spring rates, the question was directed at the OP or Scott. Appreciate the response though!

I believe the cases you refer to are people who want to get the suspension tuning just right for the way they race a car on the track. I don't think that's the case here though..

Umm correction... The standard spring rates for the "off the shelf" BC Racing ER series coilovers is 10K front and 8K rear.

Scott @ RA

Thanks, and you are 100% correct, Chris. Great explanation.
We don't believe so much in a "one size fits all" coilover package, or a complete suspension package and set up for that matter.

Depending on each individuals needs, wants, feel, etc. We like to set the valving, or split valving in this case (with the ER's) for what would be in the optimal range of valving for both high speed and low speed valving on both the compression as well as the rebound side.

It all comes down to personal preference, supporting mods, wheels and tires used, what percentage of street/ track driving they do, how harsh or plush they want the ride, the intended use of the car, etc.

For example. In this particular case with Kirksters car... We took into consideration that his car is a roadster, that he didn't want to lower his car very much at all under factory height, that the car is mainly a street driven car that will see its fair share of track use, also that the car will see more autocross than longer tracks, etc......

ChrisSlicks

According to BC NA last year the default spring rates for the "BR" is 10K/8K and the ER was 12K/10K. Did they change there default setup for 2010? Not that it really matters, the ER's are all custom orders anyway.

Thanks for the explanations Scott.

I Did the install last night. All I have to say is REALLY. No REALLY. Did they REALLY have to tighten that 19mm nut to 8 bazillion foot pounds of torque??? The drivers side came off with not much of an issue but the passenger side was a different story all together. I did not have a 1/2" 19mm so I was using the 1/2" to 3/8' adaptor. So I twisted off the head of the first adaptor and cursed a bit before I got out the second adaptor... After I got back from Sears with two new adaptors and a 19mm 1/2 inch socket the REALLY nut yielded to my 4 foot breaker bar...

Total install time minus the trip to Sears was 6 hours and 4 minutes.

With the way I initially set up the coilovers I ended up with a 1/4 inch drop after a drive to initially settle the suspension.

I decided that I wanted a bit more drop so in the morning I got started again. One tool that I found invaluable in adjusting the front shocks was a strap wrench. Without that I would have ended up taking the shock back out of the car, with the strap wrench it was a 15 minute job from the time that the tire came off to the time I finished torquing the last nut...

Total time for the full drop was an hour and 30 minutes including fumbling around time.

I will post up a review once it stops raining here, but I did get a chance to give it the boot up to around 60% before I started sliding a bit more that I wanted to given the wet cold conditions.

Initial review: 35° and drizzling:

The car feels firmer without being jarring. As far as I can tell the skittishness that was present in the stock suspension in curves completely gone. It feels even more planted than stock So far it is money very well spent on Scott's suspension setup for my Roadster.

Going to chip in here for the hell of it.

I have the same set up on my 370z and although ive not tracked the car ive managed to hit up one auto X while i was back in the states and i love the response, feel, and customization i get with the package. I still dont have them dialed in right but thats due to time and the fact im not around to do anything until Feb 2011

All in all its probably been one of the best investments ive made for the car yet.
