The New Drop is

Front: -0.8 inches
Rear: -0.5 inches

When coupled with the Koni drop I think this would put the car at a sweet spot.

Cito and altiain are th test subjects.

They are to please take very detailed notes when installing and on their test runs around town as well as the track/course.

We want to be 100% sure this is where we want to be and there are no issues.

Thank You!

Once the springs are settled I'll have the car realigned. Hope to be able to report front and rear camber adjustment range with these springs, along with "before" measurements on my car with both stock springs and the RB springs for comparison, since every car is different.

I'll be providing my personal subjective feedback, some lap time comparisons at MSR, plus some feedback and PAX results from Texas Region and Southwest Divisional events. Obviously this won't all happen overnight, but I think by the end of July I should have some pretty good feedback to offer, including track and autocross impressions.

Any other suggestions for feedback that you guys can think of?

Awesome. That's excellent news Brice!!!

That actually sounds better than the numbers that were first quoted.



Will do.

Hey, I didn't know this was a science project. I am all for it. I will post progress here.

Will we be able to request a lower drop on the progress springs? I know this maybe asking too much, but I'm just wondering because I like the spring rates... BTW who knows... they might actually look nice with the current height rating. Just gotta see some pics first!

Brice,

Quick question about the ride height drop. When looking over aftemarket springs available for the RX-8, I see that some drop the car evenly (Mazdaspeed, RacingBeat, etc) while others like these new Progress springs drop the front slightly more than the rear (Tein S-Tech & H-tech, Eibach Pro, Tanabe, etc).

Is there a benefit of dropping the front of the RX-8 slightly more than the rear? Will this leave a slight rake?

Thanks!

this is a quote from a owner of a koni challenge rx8 team owner.

the car likes a bit of rake in it!

yep, that is what he said.

beers :beer:

Not sure I will have much of a rake at all, but I am excited to find out. Hopefully, those prototype springs are cooling off right now getting ready for shipment.

are these the same as the autox springs listed ?

any news on auto springs?
dieing to try it out....

Shipping to me this week, another tested dropped out so Winning 8 you will be getting one of the prototypes to test.

At any rate, I am looking forward to getting the springs. I will document the before and after ride height, installation of the springs, and then the performance improvement. Any other things people are looking for, please let me know.
