I really need coilovers and I've narrowed down to BC BR Coilovers from JustJap... Has anyone else got this on an R34 GTT?

I'm concerned about the ride quality as I do a lot of highway driving. Also Im looking at a camber kit later on. Is this suitable with the BC BR coilovers?

Hey mate,

I'm in the same boat as you, looking for coilovers. The BC ones look good, but was also going to ask if anyone has had any experience with the YSR Coilovers? http://www.yellowspeed.com.au/

They look like a decent unit, and can adjust the preload separately to the ride height, which is a big one for me. Also look to be fully rebuildable by an Australian company, which also interests me.

Anyone had any experience with them?

Cheers,

Not sure about the spring rates. The car is basically my daily driver but I do have plans to take it the drags soon.

Didnt look at YSR mate. Heard good reviews about the BC ones and at $1140 its a good deal I reckon.

The YSR ones seem to be very stiff. Like 12/8 rates. The BC ones are typically 8/6.

You can ask them to change the springs out when you order I believe. But you're right, they do seem to come with excessively harsh spring rates.

If its a daily driver, from reading what others have done, it seems a 8kg F / 6kg R setup is good for dailying. The BCs look like a decent unit for their price, but I have heard adverse stories relating to the longevity of their design, and the comfort of their dampers. Some people have mentioned they can tend to be quite harsh on the street.

YSRs have a 33-way Damping against BCs 30-way.

YSRs have an aluminium upper mount vs BCs Rubber Upper Mount.

YSRs have adjustable camber tops as standard (Unsure of the BC ones? They look like they have?)

YSRs are $995 vs BCs $1140.

They seem to be very similar in design. They even look similar.

Adjustable camber tops not being a selling point for Skylines though.

If I were to buy YSRs, I'd probably opt for the rubber upper anyway. Much nicer than pillowballs for noise and harshness. Hardly impacts on performance.

Yeah, i've always run Rubber upper myself for the noise factory. Sure, they flog out quicker, but they aren't that hard to replace. Might be a noob question, but why are the camber tops not a selling point? I'm guessing there is a better form of camber adjustment then the tops?

The 8/6 BC's are on the soft side. In a 33GTST they are perfect for the road. If you are not going to do any track work, drop them down to 6/4 or something, iirc doesn't cost any extra. Just have to wait for them.

Whilst Skylines might have struts, they are not MacPherson struts. The Skyline suspension unit (coilover) is not a structural part of the suspension. On a Mac strut car, there is only the lower links (the control arm and radius rod) and the strut. Therefore, the location of the top of the strut is used to set the camber. Hence adjustable camber tops are required if you want to be able to change the camber at all. But Skylines have complete upper and lower arm sets at both ends of the car. You adjust camber by changing the length of any of the upper or lower arms (not that there's much adjustment stock, but adjustment can be added by putting in eccentric bushes or adjustable arms).

I had BC's in my last GTT, they were about the same stiffness as the King springs I took out of it. So not too harsh on the road at all.

They were the rubber top's

I love them & will be putting another set in my current GTT.

Should have just searched mate, this has been covered 11tybillion times. But anyway i have BC BR's in my 34, work fine, go stupid low etc. I did read through the threads and choose the BC's out of about 10 coilovers including teins, hks, and a couple of custom sets. Also spend the extra $150 and get the BR version over the cheaper one.

Don't go just jap! Also go for BC BR's

I think just jap sells them for about $1399.00

Save some dollars and go for Streettotrack.com

He has them for something like $1195.00

IMO: 8/6 is track, 6/4 is street. I live with 8/6 but on bad roads its a bit shit.

WRT the amount of adjustments whether 30 or 33 makes no difference. Some of these cheapo coilovers the adjusters do bugger all anyways according to the shock dyno, in that many of the adjustment positions are the same level of dampening. Ie, its ricey.

+1 to BC's with rubber mount top.

8/6 are on the soft side ????? Maybe for a track only car running soft compound slicks.

6/4 is definitely firm enough for street. If you think you need anymore than 6kg/mm on the front then you have some super sticky poo tyres or are a poor driver. Federal RSR will just barely utilize a 6kg/mm front spring. I'd up the sway bars a fair bit before jumping to higher springs (actually I'd bump the rear spring up to 4.5kg/mm too).

    • Nah, OEM washer bottle and brake fluid reservoirs are fine I don't know what it is with the plastic that Mazda used, some plastics, like the washer bottle and brake fluid res are fine, and still look new after 20 years use, where as the coolant expansion tank, and PS reservoir, that I replaced with new OEM items when I first got the car, turned yellow and started getting brittle a few years later If the dirty yellow stained plastics didn't trigger me there wouldn't be an issue, but they did, much like the battery bracket....... Meh As for going back to work full time to support car stuff, nope, why, because I own a Mazda NC MX5, not a Nissan R series Skyline 🤣
    • I've never heard of CJ-motor, so can't advise you on them. I'd just go straight to GCG for a GCG highflow though. Seems no point to use a middleman. I'm somewhat surprised that the price on the CJ site is lower than the GCG retail price. Even though CJ would get a discount of some sort, you would hardly expect them to give up so much margin. Maybe the price is out of date? Having said that "I'd go to GCG"...when I did my highflow, I went to Hypergear. I did this https://hypergearturbos.com/product/rb25dethighflow/#tab-dyno-results with the R34 OP6 450HP profile. With the BB centre (extra $400) and intially with the standard boost actuator, but I eventually got him to send me the high pressure one when I got to the point of being able to actually use it. Ends up costing the same sort of money as the GCG highflow, but this is, of course, the turbo that I KNOW has a shorter length core and so moves the comp cover rearwards. The GCG apparently doesn't do that. My mechanic also swears by the GCG highflow, given that we have another turbo rebuilder who does something essentialy the same as theirs, using Garrett wheels. He says it stands up at really low revs and makes good power. I haven't pushed my HG highflow past ~240-250rwkW yet (should have a little more in it, but unclear how much) and it does have a fairly gentle boost ramp. OK, it's much better now that I have gotten my boost controller tuned up on it.  A lot of my earlier unhappiness was because I couldn't keep the wastegate flap as closed as it needed to be (including some mechanical issues). I'd still prefer it to boost up nearly as quickly as the stocker, and it certainly a bit slower than that. So maybe the GCG one is worth the first look (for you).
    • Ok thanks 🙂 I will higly consider this. Any "known" company for a good reviews and experience to send that off? Is that CJ-motor good one? Or go straight to GCG site? I need to use VPN to even find some of those "shops" let alone access them 🙂 
    • You can literally put in as much WMI as it takes to quench the combustion totally (and then back it off a little, obviously), and it will keep making more and more power. The power comes from the cooling effect of the water (and the meth) and the extra fuel (the meth, which also has massive octane). It is effectively exactly like running E85. One might be slightly better than the other, but they are damn close. But with either you can lean on the boost or the timing (or both) waaaay more than with just petrol and the results are similar. Here's the first thing I googled for an anecdotal bit of evidence. Can't access the attachment without being a gold member, but it is there for the getting if able to, or searched up elsewise perhaps. https://www.hpacademy.com/forum/general-tuning-discussion/show/wmi-vs-e85/
