Any other data, post it up & we will keep this as a reference-

Remember if you go stiffer than stock you will need stiffer shocks, so really you need a good suspension shop to match both.

PM or email members and ask them what the car was like to ride in, did it chew out tyres, rip the tyres on the guards, destroy the handling....

keith-

...and Ian Booth runs his Altezza V8 on 16 & 14 for the Targa, and up to 21/23 for circuit use.

He said the Targa setting just don't let the tyres do their work on the track, and you can't run a rally on circuit setups.

Tanabe GF210 this is spring in my car

Front 30-40mm Rear 15-25mm

what is the standard spring rate for HKS Hyper-D?

Cheers guys

thanks

I put the HKS ones in today and they are far softer. OMG my Teins have racing grade springs. No wonder I keep breaking my spine on every bump. The HKS are perfect for the road.

yea they are
i jz put them on for 3 weeks now
and im loving it :D

The damper adjustment is awesome. Soft as and you can make them rock hard. I seriously didn't think it was that easy

i can't remember the rates of "HKS Hyper-D" but i got them long time ago. they feel very smooth and soft. feel lot better than my another Tein SS set on my euro.
that the feel of 2 rates spring on HKS

Hey, anyone have tried or know about the HKS Hypermax Pro for our car, Spring rate are F16 n R12, will this be too stiff for road use?

Thanks Alot

I think I have either Tein HA or SS which are hard as hell, back wheel comes off the ground trying to get up the driveway which isnt the most fun with a Torsen diff,

Damper adjustment is great though,

any people here is using around F16 R12 on Sydney roads now? any comments?
