I would change that to:
driver = 60%
tires = 30%
Everything else = 10% (doesn't matter much where you spend the money).

Hmmmm, I agree with the order.... not so the percentages....
Driver = 50%
Tires = 20%
suspension = 20%
everything else = 10%

I just believe correct suspension geometry, and function makes up for more than part of 10% of everything else......


Back to the original poster.... Grip set up is up to the driver. From considerable research I've found that rate isn't as important as RATIO. Ratio from front to back that is.... Many grip based AE86s use a front to rear ratio of between 3 to 2 or 2 to 1. For example a 8kg/mm front spring mated to a 5.3 kg/mm rear spring would give you a frt to rear spring ratio of 3 to 2. Obviously using a bit of math... a 2 to 1 ratio would use a 4.0 rear spring ratio. The ratio usually depends on 2 things... power and drivers comfort.

Drift set ups(closer to 4 to 3 or even 1 to 1) can be used in grip racing, but you have to be careful of over rotation. In most racing some oversteer is usually the fastest way around the track, but not all drivers are comfortable with a lot of oversteer as speeds increase.

Added power can compensate for a nose heavy car(as ratio moves to 2 to 1), but power and an AE86 are not always synonymous.... BUTTT if I read further you have a boosted 20V so power isn't an issue!

The easiest, quickest suspension upgrades for your car(based on the photos.....) I'd say a full TRD bushing kit, and a GReddy S-Type suspension package. Springs are bit rear biased, but overall it is the easiest, most complete set up on the market for the AE86.

There are other forums... a few have reviews and suggestions when using the GReddy kit, it will give you an idea of where to start with suspension tuning......

OH... AGAIN...DON'T forget the tires! Put good tires on it, don't dump 1500-2000 Euros into the suspension and then only 150 Euros into the tires.....
