I have the tein flex...which is plenty stiff (10k front, 8k rear rates) for that racetrack (bumpy). I have the tripoint tubular front swaybar and the racing beat rear swaybar. I did all of the pillowballs recently and inspected the remaining bushings (good shape). I have the Rotary Performance trailing arms and toe links and delrin differential bushings. It rides pretty nice and roll is very limited.

I will have to check the alignment sheet to be sure but I think I am -1.5 degree camber up front, 0 toe with -1 degree camber in rear with 1/8 total toe in. I will be on 255/40/17 Azenis RT615 so I am not expecting any record breaking lap times, but it should be a good way to feel the car out.

Cozmo, I have a set of Yoko ao48's 255/40/17 sitting in my garage. They have 3 track days on them. The bad, one needs a patch. Treadwear 60

Cool, I'll be running same size 615's as well. I've got some advanced design coilovers that I'm having valved for the car, but still need to do the bushings, which I'm not looking forward to..

This FD finished second only to the big HP skyline from XS with Tarzan driving, at one of the big time attacks. Check out what he has. http://www.xs-engineering.com/teamxs.asp?filter=1&id=36. Pretty cool he almost won with half the power

Best fawking post ever. I spend days reading every artice on that link!

Node 12-30-06 04:41 PM

yeah, thats a very awesome set of articles.
Reminds me that I need to subscribe to racecar engineering sometime

aaron: are those the high end GC coilovers? Glen said they were some nice gear.

Cozmo: Do you have a pic of the speedway style front swaybar installed?

cozmo kraemer 12-31-06 04:49 PM

I can get a picture for you...as soon as I see my car again! lol

GC only makes one line of shocks, that they call advanced design. They are definately a good bang for the buck as there really aren't any shocks near thier price (~$400 ea.) that are double-adjustable and rebuildable/revalvable. They should be pretty badass once Paul is done with them...

I asked about splitters a while ago. Can't find much. Help???

Not sure what you are looking for, but how about you use the search button and Google.

I searched for you. Here is some info:

First of all thanks for the reply. Could do without the sarcasm though : ) Maybe I should have said...1993 R1. The Fd is hard to find an off the shelf splitter for. Even more difficult with the 99 spec lip. Search button and Google....been there done that. Looking for someone with real info.

C-West has splitters for there front bumper. Bomex recently unvieled splitters that actually sit on the side of the door and above the wheel arch. As for the large wing it will help quite a bit with corner entry by creating sufficient downforce, in turn giving you faster lap times.

sleven 01-30-07 12:43 AM

Thanks RX7SIGN. Actually have been considering a C-west bumper. Have seen them around. Any suggestions where to buy? I do not need to save weight, so standard fiberglass should be ok.

The Bomex thing I am having trouble invisioning. Link to pic???

Thanks alot!

i cant see anything in that said 'article' can someone copy and paste it here ?

darkslide750 01-30-07 08:42 AM

I figure I'd get back and post some feedback on the Wing. I installed the APR GTC 200 wing and it definately made a difference. I dropped 2 seconds off my lap times. 1:11's to 1:09's at Phoenix international. I made no other changes.
The main difference is in the Nascar oval portion of the track(speeds near 90-120mph), although minor differences are felt all around. My FD still can oversteer, but it is more planted on corner exit. I would say no effect at speeds under 40 mph. Speeds 40-70 have a noticeable difference, with the higher speeds really adding downforce.
I did not notice any increase in understeer as a result.

RX7SIGN 01-30-07 09:02 AM

I have an article about wind tunnel testing done on the C-West bodykit speifically for the RX7 and how much it helped. Shoot me a PM iI know some places you can find it.

I'd like to read the articlr. Can you post it up for everyone to see?

cozmo kraemer 01-30-07 10:43 AM

1:09 is moving! Nice job, Darkslide!

Wish I could have been out there....soon....at least that is what I keep telling myself. The thread on my car is in the single turbo section titled '13BREW kit in works' by 1revvin7 (elliot) whom is building the turbo setup. Almost there!!

Good to hear the wing worked out for you but I really don't think that one piece could effectively knock 2 full seconds off a lap time. Maybe you are getting a little more comfortable with the track too ;)

darkslide750 01-30-07 01:41 PM

Cozmo, I'm in Chandler if your interested in checking out my setup. Temperature wise the engine has never got above 195F on the track, even in July with 113F outside.
Oh Yeah, hurry up and get that FD going!
Next event is Feb 3-4th at PIR again. I'm running in Nasa TT-S and the Surge Time attack on Sunday.

cozmo kraemer 01-30-07 03:19 PM

What is your cooling setup?

I was having bigtime cooling issues before the whole setup went under the knife this last time. So we have now added about 2 quarts of oil to the setup...relocated the oil filter (much bigger filter), 10an lines to and from the dual R1 oil coolers, relocated the battery, along with other associated modifications. I am hoping that takes care of the cooling but who knows??

Feb 3-4 is this weekend! I have a ton of work to do... Man I would love to go out there though.

RX7SIGN 01-30-07 03:47 PM

I will try and PDF and post it on here..

darkslide750 01-30-07 04:03 PM

I have two big oil coolers and a self made V-mount setup. Works great. No AST. Oil temps rarely get to 200F.
