S13 Front conversion help (S14/S15?)

[asyrigos]

I have the S13 front conversion for quite a while (4 years) with numerous track days and I am very happy with it. It's 4x114.3 and I am using the stock S13 breaks which are more than enough for my horsepower 160hp 4AGZE).

I didn't see any reason so far to consider an S14/S15 conversion.

There are a couple of important points though to make this a success:

If you intend to lower the car significantly you definitely need an S13 roll center adjuster to correct the front geometry. I am using the Nagisa Auto one and I am very happy with it.

You need to test and tune the S13 suspension for the light weight AE86. Most of them come tuned for the heavy front weight of S13. This means lighter springs and different valving of the shocks.

Haven't experienced any bump steering or other issue so far but got my eyes open for it.

The only drawback is the heavy steering wheel but I can leave with it....

If you need anything else let me know.

If you need 5x114 then you need S14/S15 suspension. If you have 16" or larger wheels then it makes sense to go after an aftermarket front hub which will roll center as well....
