Yellow Speed Racing coilovers

[Regie]

[quote="Regie" I have found them a bit bounce in the rear, but i will let them settle first before i adjust anything.

good stuff. Report back what changes you make, if any, and for what circumstances. As in road or track [/quote]


good day today, those shocks rock on the track, started off with winding them up 5 clicks from full hard, nice and stiff through the corners, second session put them up full hard, and man its rock solid around the track.
after some mucking around with the setup in the arvo and some tips from the 5th gear instructors i dropped just under 4 seconds off my morning time.

i feel to go quicker ill be needing a proper seat and harness, im sliding all round the place oh and some R specs

best $1K ive spent

Ill do a full report in the coming days, im off to bed...im rooted! and want to hit the surf early in the morning

so Regie how were your lap times compared to koni/king combo? And is soft setting on the street quite comfy?

You know, these look VERY similar to my G4 coilovers.

[zorak]

...which look similar to BCs

[RG.net]

The BC's don't affect spring preload on the rear though, the whole design is different to these.



There Yellow Speeds appear to be identical to the G4/D2/K-sport range, just coloured like BC's.

I'll be switching my G4's out for some BC's soon, I'm sick of the bouncing in the ass end of the car.

[zorak]

You're right RG, I only looked at the fronts - kind of weird to have spring and height adjustment on the front but not the rears?

[Regie]

mine look exactly like those BC's

mine was the first set to have adjustable shock bases on the rear as well as spring perches

[RG.net]

Now that's interesting!

So they might have switched suppliers which produce the BC's?

I'll need to get a ride in your car Regie, before I go on the hunt for new coilovers.

Hey Guys!

We asked Yellowspeed to develop these coilovers with the adjustable base to compete with rival companies. We used these last weekend in the Wakefield 300km race. The Mx5's that finished 1st and 2nd both had the premium competition coilovers in them..
David also did a 1:06.8 in Goldie during the weekend... (there is no turbo on that car )

Hear are some pictures of both types of coilovers which all now have the adjustable base at the rear.

Would someone be able to give me an idea of how the new ysr coilovers stack up to the BC ones? I've been looking into getting a set of BC's for ages but recently been reading up on the yellowspeed coilovers and I'm unsure which to go for. The YSR are a lot cheaper but seem far better value, especially the competition spec ones with the heavier springs.

Would anyone be able to get some light on this? Because even the highest performance Yellow Speed Racing coilover seems cheaper than a set of BC's.

[Mr nanotech]

Sooo, anyone give me any feedback to my question?

[Mr nanotech]

What I find odd is that BC V1/VA series is virtually the same price as the BR series which is their premium model... And a lot of forum sponsors only seem to stock the V1's now... Which sucks.
So without having to import and pay around $1300, the YSR top model with the heavier springs clocks in just over a grand... So it makes me wonder where the better value is. I can't see any comparisons online though because nobody seems to own the YSR ones. Maybe they just aren't established yet so they're cheaper?
Thats the only thing I can think of because everything seems to indicate that the top YSR are better than the BC BR series coilovers.

I don't know that you will find a lot of comparison reviews. Some will have BC, some will have YSR. Considering they are aimed at the budget end of the market, I doubt anyone would swap from BC to YSR or vice-versa.

I would imagine both are very similar and as a YSR owner, im glad i saved the $$$$ (and grabbed them from a forum sponsor). Now the set I bought didn't have the sleeve height adjustment in the rear and I didn't see it as an issue then. Now the new YSR's have this sleeve I can only see them as direct competition to the BR's and had I waited, I wouldn't hesitate to grab the YSR's

I have a set of BR bc's, I think they are good value for the price you pay, I purchased at the budget end of the market as I was not shore what combination ( spring rate /valving I wanted). I am changing spring rates how, so I had the shocks dynoed to see if they would suit the new springs. I was very suprised, and happy to find that the valving on all four shocks, was fine and they all graphed at the same rates. ( I think alot of people would be very suprised at how inconsistent some high end shocks sets are). Performance wise not to bad, the nose rates were a little low on the soft settings, which is very common for a shim stack type valve, and I have only seen "Penske", able to address this issue ( mega bucks). Even though the adjuster is said to be Comp/ rebound adjuster,it mainly changes the rebound with very little change in comp ( which is excatly what you want ).
The only faults I see with these shocks and any other brands with the height adjusters ( not the preload ) is to achive this function the shock body is shortened, which reduces the stroke of the shock. So my BC's have 90mm of front travel and the rears 60mm of travel, I don't consider the rears to have nearly enough. I would preferr F 120, R100mm out of a performance shock, so I have now increased my spring rates, to reduce the suspenion travel I will need.
So if I had to buy some budget coilovers now, I would go for the YSR , and try and get the old ones with out the rear height adjusters.
P.S my car is mainly used on the track, and the lower wish bones sit level at ride height , approx 1'' lower front and 1 1/2'' rear from std.
