Best coilover for the money

[Brad]

HI Brad
What spring rates do you use?
Where do you do most of your racing?

Rates are 7/6kg or 392/336lb

I don't race myself. just trackdays, but have a few friends in the Production Sports Car series.

or your mrs when you're off racing

With regard to spring rates, I use Kings on AVO's at 350lbs fronts and 250lbs rears.

I think ride quality would be pretty good, due to the adjustibility of the shock - you dont reallly need seperat to get comfort. My coilovers came with 5/4kg springs standard and i put 8/6kg in there and on the softest setting they were smoother than my old teins. While this doenst coment on the quality of the G4 units i'd say they would be plenty good, try it and see!!!

I have been led to beleive that with bump, and rebound, i would be able to run harder springs, and yet get them to ride softer for the road.

With the ability to have soft bump and harder rebound ,to give ride comfort, not handling, Or to crank up the bump for better handling.

I'm happy for you to tell me how wrong i am,But if you do please try to explain.

Don't disagree totally but in a light car, you need compliance in the suspension to keep all the tyres in contact with the ground firstly and then to control the frequency of the spring movement. You do not want to run super hard springs as it will make the suspension work against the chassis. The USA spec miata guys run 700lb fronts. Locally, about 400lb is all you need because any stiffer and the front wheels will bump off the track surface thus losing you grip and increasing braking distance. That's because our tracks are bumpier. Like our roads.

So for most of us, combined bump and rebound is fine because it adjusts within an acceptable range. That said, some shocks have better damping curves (the way they react when adjusted) than others. I believe this is where Teins are very good. )

So what spring rate do you recomend on the teins for street and race?
Most road is a bit rough,but i dont want the front to bog in corners.
From what i've read, mx5's need fairly heavy front ,compared to back,It has been said a number of times, that the hard front keeps the car flat,But the back needs to be softer to keep drive to both back wheels.Maby some of this bias is for the guys without LSD?
The tein's dont seem to have this big spread in spring rate.
Whatdo you think?

[CT]

Not totally true but it depends on your chassis. For example:
NA cars are softer in the chassis and require a softer rear spring. A spread of 100-150 pounds in not abnormal front to rear assuming a matched sway bar set. I had 392/260lbs in Tein Flex on my racer but only ran an 11mm rear sway because it had a welded in cage and the rear was stiffer than a road car would be.

NB cars are much stiffer in the mid and rear of the chassis due to extra gussetting and bracing. They can run a stiffer rear spring so a spread of 50-100lbs is probably more suitable. I have a road NB8B with Tein SS 283/200 or something similar in them. They are great for a street car. The SE race car has 396/336 Flex. The PSS9 bilsteins have the same rates front and rear (383 I think) but may also require a thinner rear sway to keep them neutral.

Tyres and driving style will also make a huge difference on how you like the car to feel - so will alignments. But from my tinkering over the past 7 years or so with MX5s, I think the above is a reasonable guide. The SS coilovers in the NB8B totally transformed the car and increased balance and grip so I reckon they must be pretty good things.

My car will be runing 17-8 front 17-9 rear 40 offset but with 20mm stud adapters so i have a wider than standard track.

It is my understanding that the wider the track need heavier spring rate to compensate for the extra leverage on the suspension,and the heavier wheels.

What do you think?

[Cal]

I think you should get a nice light set of 15's and I'm sure Chris will agree. The wheel is about the worst place on a car to carry weight. Some Volks I have weigh 4.6kg each.

None of the race cars in NSW use AVOs. All the fast turbos are using Teins except Brian who is using bilsteins while the NA cars mostly had koni yellows or clubman bilsteins .

Must be why they (non-turbo) are loosing to the Qld boys then huh?

I think Chris missed this comment so I thought I'd highlight it again

Thanks Neil, gee not sure how I missed that one.....must be my eyesight failing or something! Which you have seen evidence of first hand at PI funnily enough!

The 17\" wheels are for road use and looks.

I will be using 15\" for racing,
I'm still looking for the 15\" wheels ,There isnt many available over 7\" wide and i would like to run 8\" front with 205's and 9\"rear with 225's.

If you have any places to get the wide 15's from please let me know.

The best i can find is speedy 8\" cross 5 rims ,but i have asked about weight and got no reply.

[Cal]

No idea mate. Everybody I know uses 15x7's. Why do you want 225's? We get some rubbing from 205's.
