P5 w/Racing Beat springs - call for photos

[JoshP5]

Anyone put Racing Beat springs on their P5? I'm not talking about those MSP or MP3 springs (those are different), I mean the ones you can buy *new* from ProtegeGarage or directly from Racing Beat.

I'm thinking of getting some but would like to see what the drop is like on a P5, so if you have this setup please post a snap or indicate front and rear wheel gap measurements if you have them. Thanks!

[Reitrof]

I think AMAff does.

[redpr5]

the drop is almost unnoticeable from what ive read and seen. if you park a reg p5 next to one with the racing beats you can tell a lil bit. but the drop is so small with the racing beat springs its not much different

[JoshP5]

I think AMAff does.

Nah, I think he's running MSP springs.

[ho bag]

Doesnt MSP spring=Racing beat springs?

[AKYellow]

^^^
yeah they are RB springs

[JoshP5]

No, they're not the same springs. The RB springs you can buy from RB were originally designed for the MP3. Mazda eventually decided not to use them, rather a taller/softer set was used on the MP3.

The MSP had still different springs with revised rates due to the additional weight of the turbo/intercooler/LSD.

The RB springs available from RB are stiffer than both the MP3 and the MSP springs, particularly in the rear.

didnt RB make the springs for the MSP? Thats what I thought anyway.....

Actually, RB doesn't make any springs. They have a supplier which makes the springs to their specs.

When I contacted RB about the MSP springs, they indicated that Mazda isn't very forthcoming about providing the spring rates, so they couldn't say what the rates were for sure.

I did get specific data about the RB spring rates - 162lb/in front, 111-190lb/in rear.

Nobody has tried these springs on the P5?

[AKYellow]

I stand corrected!

Thanks for the info.

on Racing Beat springs with 40 series tire

now I have Espelir springs which drop a little more but it's even all around

so I still need to sell my (slightly used) RB springs... interested??

Thanks for posting that shot--your car looks great! That's the kind of subtle look I'm going for. The unevenness isn't that noticeable there, although I realize that angle tends to hide it.

I may be interested in your RB springs, but I'm still debating between those and Tein H-Techs. I ran RB springs on my Miata and was very impressed, but it looks like I'll have to fabricate/modify the rear spring seats on the P5 to level out the drop with the RB springs. A few questions:

EDIT: Searched a bit, got some answers:
1) Are those Mazda3 17s? Yes
2) What kind of struts did you use with the Racing Beat springs? Stock
3) Can you verify RB's claim of 3/4" drop up front and 7/8" in the rear?
4) What are your observations with the stock/RB/espelir springs in terms of driving dynamics?

1) Yes those are Mazda3 17"s
2) Used stock struts with RB springs / now use Tokico HP (blue) Struts with Espelir (Active Super Down) springs
3) To verify that it's a little lower in the rear click here Racing Beat (http://www.racingbeat.com/resultset.asp?partnumber=74010)
4) I don't autoX so I don't really feel like I can say much about the difference in driving dynamics between the two springs but check this link and you will notice that the Espelir (http://www.espelir.co.jp/index1.html) springs have a different coil design.

The Espelir springs are designed to get stiffer the more they are compressed I think. So my hope was that the ride would be a tiny bit less harsh than the RB springs.

I just wanted the best streetable suspension. I didn't shave my bumpstops so sometimes I get jolted when I roll over a big bump in the road.

One thing though, the 40 series tire makes a big difference in ride quality buttocks wise. For the winter I went back to the stock rims with 50 series tires and it's like I'm riding on a cloud in comparison. So now I'm also thinking about selling the 17"s too since I'm moving accross the country soon.

Thanks for the compliment - I recommend Rishie with AutoRnD (http://www.autornd.com/catalog/) (p5silver)

The RB springs are linear up front, progressive in the rear.

This was my experience with my Miata--since I trimmed my bumpstops, my feeling is the struts caused this. Too much damping for the RB springs on rough roads.

Espelirs are linear in front, meaning they have a consistent compression throughout the spring...This give a better feel for turn in, and consistency through your turning arc... They are progressive in the rear meaning as the spring compresses, they become "stiffer" giving a balance of ride quality and performance....

Espelirs are the best...

FYI I sold my racing beat springs to JoshP5.
