I ran my stock suspension on my E30 last week at Summit Point. A wild (and slow) ride to say the least.

I'm shopping for a full upgrade to a race suspension. Turner sells a "J-Stock" kit for the E30 that contains "all you need" for about $1800. Does anyone have any experience with this kit? Any tips on installing it would be helpful. Does it really contain "all I need"?

While I'm upgrading the suspension, I thought I might replace the A-arms with aluminum ones. Any suggestions?

If anyone has any other suggestions on suspension and steering upgrades, I'm open to your thoughts. Thanks.
