Porsche 997 GT3 Coilover Testing

Posted on by

You’ve read that correctly- we’re now testing on a 997 GT3 Porsche with our very own 3-way adjustable dampers! While Porsche’s aren’t necessarily anything new for us, we’ve only made a name for ourselves developing and producing products for the Japanese vehicle market (JDM, if you will). But, with increasing demands for products internationally, the TEIN group has branched out into other vehicle markets and made some unique suspension setups, specifically for rally and off-road. Our expertise doesn’t stop there, however. We love road racing, too. This latest example is no exception.

This past year, the TEIN group has been working with a few customers (997 GT3 customers, specifically) wanting better suspension than what the car comes with, and what was currently available as aftermarket. Off the lot, the GT3 is pretty hard to beat, or in this case, make better. So that sounded like a great challenge for TEIN engineering!

So, while TEIN Japan was taking care of overseas inquiries on this, the TEIN USA group had a customer who was just as interested. It turns out our good friends at Evasive Motorsports had a 997 GT3 and were going to start developing the car for track duty. That was a good coincidence!

Anyway, we finally got the prototype 3-way adjustable dampers in from Japan and headed over to Evasive Motorsports to do the install. So far, so good! First reports from the owner is that the car’s ride quality has improved! Next up is some track testing, which we’ll report on soon. So stay with us as we get more updates!

Here are a few pics of the install with Evasive Motorsports for now!

Spring Seat and Seat Lock Evolution

Posted on by

Since the beginning, spring seats and seat locks have been a necessity for the systems ranging from our Type NA coilovers systems utilizing a three position adjustable perch on the shock body with locking snap ring to maintain the seat position, similar in design as the Koni and Ground Control set ups, all the way to the Street Advance coilovers which utilize a spring seat lock with a delrin thrust washer and seat lock to maintain the ride height position on a removable threaded sleeve which is ZT coated.

The photos below detail the different changes made to the spring seats and seats locks over the years.

The Image above is of the spring seats for the Type NA damper which, as mentioned, used a c-ring that would be placed in the desired ride height setting.

This style which utilized a spring seat, seat lock, and aluminum thrust washer as shown in the photo above was the second design released for multiple coilover kits ranging from the older style Type H2, Type HA, Basic, and Super Street, all the way up N1 coilvers as shown in the photo.

This third design which is still used with some of our coilovers today utilizes  two seat locks and 1 rubber spring seat.

This photos show the newest type of spring seats and delrin thrust washer in conjunction with the previous style seat lock which are found on the Street Basis, Street Advance, and other coilover kits both currently available and future release.

Although the material and coating has changed over the years, it would still be recommended to periodically clean and lubricate the locks, threads, and locking rings, depending on the model type. This will ensure years of trouble-free height adjustment for your TEIN coilovers.
