Enkei RPF-1 17x9, 45mm offset 5x114, 15 pounds

WedsSport TC105N 18x9 +50 - 7.7 kg or 17 pounds

Not sure if these will fit, but the offset look about right:

Enkei RC5

19.5 lbs

Heavy, but I do love Enkeis:

Enkei RPM2
18x9.0 +35
21.1 lbs

That's a very popular wheel for STX WRXs in a 17x8 size.

http://www.good-win-racing.com/miata...ing%20RPF1.jpg

If I decide to run STX in 2010, I'd strongly consider 17" wheels only if the competitive ST tires are offered in a 265 width in this wheel size.

refresh my memory... the rules for stx wheels are? (too lazy to re-check on scca)

max 9" wide wheels for 2 wheel drive
max 265 tires

dia and offset open?

Yes, in STX diameter and offset are open.


I got used set of 245/45R17 RE01R's for crazy cheap so I'm thinking about finding a cheap set of EVO VIII Enkei 6-spoke wheels to start (17x8, ET38, 67mm CB). They'll work well for track wheels once I get a real set of STX wheels.

Are you doing a full STX conversion? Watch out for Cline's BMW -- it's FAST!!!!!!!

Will all these wheels clear the RX8 brakes?

Cline is fast, he'll be a good benchmark for me as I buildup the car.

More wheel options.

Although quite expensive compared to some of the other options.

BBS RGR (forged, 17.2 lbs) 17x9 ET42
http://www.tirerack.com/images/wheel..._bsp_ci3_l.jpg


For 17" wheels I think that the $250, 16lb, 17x9 Enkei RPF1 is the way to go for STX.


For 18's the Volk RE30 is the wheel I'd be dreaming of. Forged, 18x9 ET40, 17.5lbs and $796each.

Right now I'm also looking at the last of the 19.2lb Kosei K1TS 18x9 ET20 wheels from Tire Rack for $200 each. Not sure if they'll fit but it's a hell of a deal if they do.
http://www.tirerack.com/images/wheel...s_lg_ci3_l.jpg


Budget STX'ers can get the ASA AR1 18x9 (ET45 23.8lbs) $174 each.
http://www.tirerack.com/images/wheel..._ar1_ci3_l.jpg

Is that offset correct? ET20??? If so, those will stick out significantly from the sides of the car.

ET20 is right. If they fit it would be nice but I'm not sure if they will. I know TeamRx8 ran 18x10.5 ET43 wheels and these 18x9 ET20 wheels will stick out the same amount as a 18x10.5 ET40. Tire profile when mounted and the 3mm difference is what I am worried about.

The tire size is the same, though. Team was running a 265 Yokohama, and if I recall it was a tight fit. The difference between +20 and +43 is almost a full inch, so you'd have to gamble that a 265 on a 9" rim is a full 2" narrower than a 265 on a 10.5" rim. I just don't see it happening.

I think Team tried different wheels - not sure if these were the ones you mentioned:

https://www.rx8club.com/attachment.p...id=77750&stc=1

https://www.rx8club.com/attachment.p...id=77751&stc=1

https://www.rx8club.com/attachment.p...id=77752&stc=1

If the fit is close you could always legally roll the inside fender lip.

Unless there are 265/17's out there, the 18x9's are going to be the way to go.

Now finding them is hard. All sorts of 18x8.5 and 18x9.5's out there. Its like they made the required size 18x9 just to make it more difficult and expensive...I know they didn't....but....

Besides wheels, any thoughts on coilovers, sways, intakes, etc.?

No idea on weight:

Rota Boost 18X9 +30mm
http://www.rotawheels.com/images/products/boost_1.jpg

Here's what I ended up getting.
Weds Sport TC005
17X9 +42
15.8lbs

They were on close out on tire rack for $240, normal price $370. I'm not sure if they are still there or not.

Those are his 18x9.5 Enkei's the wheels I was talking about are the SSR Comp-H 18x10.5

https://www.rx8club.com/attachment.p...6&d=1179874432

https://www.rx8club.com/attachment.p...9&d=1179874432


The TC005 is one of my favorite wheels of all time. It's a shame Tire Rack didn't pick up the wheel WedSport replaced it with, the TC105N.

From what I can tell, about 22 pounds each.

Might be more like 23.5 pounds. Its a bit of surprise given that they look so much like the good ole SSR's.

Speaking of STX wheels and tires. On sccaforums. Wheels and tires that should fit (may or may not need hub centers masaged).

http://sccaforums.com/forums/1/33076...ad.aspx#330766

One issue with 17s is I don't think they'll clear big brake kits on the market. This might be important for a STX build as BBKs are a good source of weight savings.

Good win racing has stock size lightweight two piece rotors.
http://www.good-win-racing.com/Mazda...t/60-1260.html
http://www.good-win-racing.com/Mazda...t/60-1261.html

This is where Ulllose's point about paying more to go slower starts to make a lot of sense. Those rotors are freaking expensive.

And someone forgot that there is weight to be saved with the caliper as well. $$$

Gotcha Miles. Quick question, any idea what the weight and price are for those 18x10.5" SSR's???

Weight = Supa-Light Yo! 18-19lbs IIRC

Cost = $infinite. Sadly they are no longer made. I beleive that the set Mark bought was one of the last sets available and that was around a year or two ago. I think TireRack listed them as a rear wheel for the NSX, not sure though.

I don't know of a comparable Type-C RS or Type-F but my wheel info resources are very limited compared to when I worked at TR.

You like gold wheels right? These are a slightly heavier version, the GT2, made by SSR that someone on the forum has/had for sale.

Only if you're building a dedicated autocross car.

If you're building a track car that you want to autocross in STX then the point is moot. On the track a STX prepped car + comps > BS prepped car + comps. Well as long as its the same driver.

Regardless the thread is looking for STX eligible wheels not discussions on the merits of the 8 being run in a different class. Since BS may be going the way of the dodo - or the 8 possibly losing its crown as BS preferred ride - enouraging people to branch out a bit might not be the worst idea in the history of this car forum.

Thanks Miles. I <3 gold and bronze wheels from my Subaru days! :lol:

Those SSR's are just the ticket. Not looking for a set at this moment, but I've decided that I'd probably like to run in Street Prepared in the not-too-distant future. The current RX-8 would be crushed in BSP, but I'd possibly like to give that class a crack when the 16X renesis is released.
+1 A similar progression occured with FD RX-7 drivers who went from SS -> ASP -> SM2.

I think some people should write letters to the SEB asking for the RX-8 to be moved to DSP. It just got dropped to STX, where it will compete with many of the same cars it would run with in DSP. I think it would be a very good match for DSP BMWs. :uhh:

These are super nice...17X9" with whatever offset you want...15lbs.

Order 'em now and have 'em by Christmas...2009.:lol:

http://i33.tinypic.com/2iau83o.jpg

Would that be the first set, or the set that fits the car and holds air? :eek: :rollingla

Someone should see what these guys can do: http://www.jongbloedracing.com/

I hauled a set to Wendover last year for a guy, the quality looked great, and I understand they are fairly light for a 3-piece.

I would say wait a few months, can't run an RX-8 in STX yet anyway, and see what sizes that new OZ comes in.

Jongbloed is up here in NorCal and I've known guys who have run their wheels in club racing for years...they have a great reputation for making road race wheels. I spoke to them about making some stock class legal wheels for the RX8 a couple of years ago and ended up not going down that path. The price was a little over $650/ea, as I recall, and they didn't think they could get them below 17.5# using their centers, which they admitted were beefier than many of the more autocross oriented wheel makers might spec. At that point, the $300/ea, 18.4lbs OZ looked even better...

That's almost worth starting an Andy Hollis style thread on sccaforums. I would lie if I said that thought didn't cross my mind...

It has crossed my mind several times.... But as long as I am on the SEB I stay away from RX-8/BS related topics - but it can be someone else's baby. :)

Put together some BMW/Subi/RX-8 dyno charts, along with weights, potential areas for improvement from stock/ST to SP, and I think you would have a good letter on your hands.

Don't look at me to start one...while I wholeheartedly agree the '8 is a DSP car:

a) The only RX8 I'm driving, going forward, is someone else's

b) I've already pissed enough people off by running with the "XS sucks" idea

I'll bounce this idea around through pm to a bunch of people I respect. Doug Rowse trophied in Spiedel's RX-8 and won DSP this year in a BMW. Pat Lipsinic has trophied twice in a DSP 2.5RS. Nathan Whipple trophied this year in a DSP ITR.

<<My thoughts>>The RX-8 is a dead duck in the current BSP. Even the new "mid-pack" cars of the class (E36 M3, C4 vette) will run circles around it. It also doesn't have the torque or light weight to keep up with a CSP miata. DSP sounds like a good class for it...<</My thoughts>>

Oddly enough I had an rx8 to DSP conversation just a few days earlier... From my perspective it would be a interesting fit, but I think it would likely dominate the class.

Not sure on fitment, but size is right:

Enkei GTC01
18x9.0 +40
23.1 lbs

http://www.tirerack.com/images/wheel...rblk_ci3_l.jpg

Here is an interesting one....

Enkei RPF1
18x9.0 +35
18.4 lbs

Special order from Tire Rack for $338 ea. (Lexus IS350 fitment):

http://www.tirerack.com/images/wheel...f1_s_ci3_l.jpg

Very expensive, but on clearance at TireRack:

Volk TE37
18x9.0 +40
18.5 lbs
(Lexus IS350 fitment)

http://www.tirerack.com/images/wheel...7_Ti_ci3_l.jpg

+1 to moving the RX8 to DSP. BSP is a cruel joke. Also, I could have plenty of fun in DSP with just a tire change from STU.

I feel it'll be course dependent. The RX-8 is similar in size to the E36 & E46 3-series, IS300, while other cars like the 2.5RS and ITR are smaller. It has an ITR powerband, but E36 BMW weight. I don't think it'll dominate, but it'll give it a competitive place to play. It's definitely not suited for BSP or CSP and it'll completely out-handle the ESP camaros/stangs.

FWIW, I started a new thread to discuss the RX-8 in DSP: https://www.rx8club.com/rx-8-racing-25/rx-8-dsp-160070/

Another uber wheel
Volks ce28n
18x9
+35 or +40 offset

or 17x9
15, 22, 23, 35, 40, 54, or 63mm offset

In the 15" wheels IIRC the ce28's were lighter than the te37's

^ I coughed when I saw the prices of those Volks. I knew they were expensive --- but WOW!!!! :eek: :eek: :eek:

You're right. But I wouldn't be suprised if they are the lightest available (at any price). I picked up a 15x6 te37 and a 15x6.5 ce28 someone had for a Mr2 spyder and was shocked. the ce28 was less than 6#!!!!!!!!!!
