Definitely not. The Spec Miata Bilsteins were designed for smoother circuits than actually exist in the real world. Our SM customers strongly indicate YES, Elite tuning makes you faster! If you watch our 'How Shocks Work' series for Spec Miata, you'll see where improvements can be made. Even brand-new shocks have large variations in rebound force, something only a shock dynamometer will reveal.
Expect lower lap times by 'a second plus'. You'll bottom out less, handle rougher tracks much better, keep the car on the racing line more easily, and have more grip (especially in wet or dirty conditions). Imagine that - a faster AND more comfortable race car: win-win! Run your setup the same way as before. You can have us change the shock oil every couple years of racing.
Yes, our work remains legal for NASA Spec Miata racing. As of 2018, the all-knowing, all-wise SCCA SMAC indicated that shocks cannot be modified, so our work is not legal for SCCA Spec Miata racing. Apparently $9,000 'pro built' motors make complete sense but it's bad for the class to keep a shock spec that's existed for years (until we made some videos). We feel sorry for you SCCA SM racers!
FCM-SM-MAX valving is $450 per corner. Our Ripple Reducer feature ($125 per corner) is automatically included to optimize the setup. Yes, you need it. We're usually able to complete a build in 7-10 business days non-expedited, or 3 days expedited (30% extra). We prefer that you supply us the 90-97 Miata Bilsteins.
