I'm going to be upgrading springs on my daily that will occasionally see a road course/autox day. I'm wondering if anyone has some experience tracking their 3's and what springs they're using. I'm leaning toward either h&r or racing beat because they seem to be a bit stiffer than prokit/corksport.

From my research, I'd recommend the Racing Beat springs over the H&R on a daily driver, simply due to the scrape potential of the lower H&R's. Are you replacing shocks, too? Degraded service life from OEM with the H&R drop is something to consider on a DD (though they'll likely last a bit).

I love the height of the pro kit, but will cave and add the RB springs in the near future, along with some Koni shocks. The roads in SC are miserable.

From my experience, I have not scraped anything on H&Rs. The drop is not as bad as some make it out to be. They do seem quite a bit stiffer than stock though. You will need to upgrade your shocks for best results. OEM shocks don't usually play well with stiff springs.

If you are going to do autox or track days, you might also want to consider a rear sway bar upgrade depending on what sort of classes you will be running in. That and front camber plates can make a huge difference in how your car handles.

Ok thanks for the input! I won't be doing sway bars or shocks (maybe a progress rsb if it's completely necessary). The life of the shocks should be just fine I've done some work with shock dynos and suspension design. It'll just be occasional as I'm hoping to be getting another car for dedicated track duty and subsequent money draining. I'm thinking I should do racing beats as I'll have to drive in MN winters, but I love how the H&R's look.
