Yellow Speed Racing coilovers

I tighten the collar for more low. Slackening it off raises the ride height.

and of course I got that wrong

When I installed mine I had guard scrape and had to wind up the collar to raise it a touch.

Dude you don't tighten the collar over the spring. When you max out the cars lowest setting using the lower height ajustment spring, you can further lower it by slackening off the collar the springs sit on. However if you want to go propper low, the trade off is that you will nolonger have captive springs and the springs will be floating.
With helper springs, you can wind the spring collar out and get the car low but at the same time keep them captive at all times. Therefore you can slam the car if you wanted and still have captives.

Having helper springs will just make things less clunky with the lower spring perch wound down. That's it.

You said the YSR rear height is weak at the lowest adjustment and sounds like you think helper springs will help to get lower...?

Personally I would just get springs 20mm shorter if you are trying to so lower. A helper spring when compressed will be 6-7mm thick, so actually adding height to said car. So you really have to wind down the spring perch/foot to compensate for that also. Hence also reducing shck stroke and the shoke's effectiveness.

Bingo

That video just repeated what I typed. Personally I'd still do it the right way. Yes the right way might cost more. But at least it is right. But looking at that video, a short damper might be a better choice than a shorter shock.

My 1st coilovers (JIC Magic) I ever owned has helper springs, but that was cos they were the old skool design like Tein still do. Only height adjustment on the spring perch. So when they were lowered, the spring became non captive.

Since then I have had D2s, BCs, and now Yellowspeeds. All with hub knuckle height adjustment. The D2s were great straight out of the box. The BCs spring perch was so far off the 2 springs were not catpive out of the box, but no way to tell until they were on the car. The Yellowspeeds I ordered 2 days ago, time will tell how they go.

YSRs turned up today. REmind me very much of my old D2s, with a few subtle differences.

So, any further thoughts/updates on these coilovers?

I had to spend another $150 to make mine fit correctly. (Not a MX). Other than that, a very good coilover for the price. I shock is better than BC.

[aka_juffa]

shock is better than BC.

Thanks. In what way(s) is the Yellow Speed better than BC?

I rate them highly, but don't expect plushness and comfort. They soak up smaller bumps, but drive on bumpy roads like Botany Road in the City or bumpy concrete sections of the freeway and you're on a fairground ride. It's not uncomfortable on bigger bumps but they're not effectively soaked up either.

If spirited driving is your thing, these are more than good enough. A mate who drove my car last weekend said it rode just like his old Exige which had Nitron Coilovers, I can't argue with him.

If you want a plush ride, get some Teins.

As far as lowness is concerned, I can't comment, mine is set a little higher than recommended so the additional bracing I have under my car doesn't make contact with immovable objects like speedhumps or ridges in the asphalt so much.

[Jace]

Not enough base-height adjustment on the rear coilovers but they are by far the most comfortable coilovers I've owned.

Any feelings about whether changing the ratio between the front and rear spring rates causes more over-steer on the track?

[project.r.racing]

My old BCs had a 6/4 spring combo, and my current YSRs have 8/5 spring combo. I was expecting a increase in teeth shattering harseness. But they soak up the bump just as good.

Cannot comment on ride height, as the YSRs are not in a MX.

Thoughts on front/back sping ratios has been discussed in this thread. Read a few pages back.
