Best Springs to match bilsteins ae82 gt

[Kiwi6539]

Hi what spring rates would be best for race car used on the road. Staying with shock spring set up.

Bilsteins HDs installed with dobi lows but a little soft for me.

Also best place to get a full set of bushes front and rear?

Any advice or if anyone has stuff to sell would be great

hey, cant remember AE82 and AE92 swap over as my supsension little to hard would be great on race track

Hello I tried to text but number won't let me.

Do you have advice or Springs to sell or swap?

[gepsk8]

Number is correct, might have already found swap.
If AE82 fit AE92 could be keen on swap

for a road setup I would recommend 450lb front, 500lb rear for an AE82. Compliment with upgraded swaybars to whiteline if possible.

This is a fairly soft an compromising setup will sill get plenty of travel and compression under braking and cornering just make sure you are using decent tyres and it won't be a problem.

For the road I would go more like 6k front and 4k rear.

Track the rates go the other way around.

[touge_ae101]

Have you tried those rates for the road and track? They are waay to soft for either.. of course depends on your sway bars but you just end up with heaps of Tyre roll and a sloppy feeling.

Ae82s need a slightly stiffer spring than you would expect to run on a ae92 or Ae101 or ae111 as they have a very high Centre of gravity, they are approx 100 mm narrower and also their LCAs are shorter than the layer models. This leads them to lean over a lot in the corners and wear outside edges like no tomorrow.

You don't even want to know what we are running in the racecar now to get it to handle right and stop wearing outside edges...

Race car to road car is totally different Reece.

I've sold heaps of 6/4 setups and that was on the customers limits for road use.
I even had to supply 4k to the fronts for some customers.
You try sell a customer higher rates for road use. They will come back to complain its too stiff.
I've sold over 50 sets of AE82 specific and guys have been pretty happy with the rate. The guys who like track have been using 10/12k on semi slicks.

Yes I agree for track you need to be much stiffer.

The track is a totally diff story when running slicks. Your car is like a go kart.

I suppose it does depend on what people's perception of 'stiff' is. If they want a spring slightly stiffer than a lowering spring then 6/4 is about ok. If you want the best performance for road and not really fussed on comfort then 450 front and 500 lb or higher rear is what you need if it's to be used for hill climbs or sealed rallies etc.

I ran 400 lb front and 600lbs rear in the Ae101 on the road and was definitely not too stiff never had snap oversteer and sat very stable on some very rough back roads I frequent.

For the average driver maybe not but if your pushing it (say in a 'sealed tarmac motorsport event' :p), then a stiffer spring will bring a lot more grip and better stability. Doesn't work if you are driving like a pussy or have shitty tyres though

lol, the way we think of whats stiff and soft is prob most different to the normal guy.

lol, our perception of whats stiff and soft is prob most different to the normal guy.

Be careful of what you're typing there Baz.....

Bazda sold me set ISC coilovers for my road car. 8kg in front, 6kg in rear. Was way to hard for road car. Would of been great on race car.
Changed springs to 4kg on front and 3kg on rear made no difference as shock rated to hard.
Waste of money and time.
Depends on budget very cheap option is to get lowered spring and cut down spring carefully to remove softness.
Or if got bigger budget get some harder spring with rates like Bazda and Touge AE101 suggest.

Yes the last batch of ISC were quite stiff (that must of been 3-4 years ago now), thats why we dropped them as a supplier as they didnt want to valve to them to what I wanted anymore.
Our new range though is 100x better.
