Because I was asked, here are the part numbers for the spring and the cover:

 

Saturday's autocross if anyone's interested... I wasn't a fan of the course, it had a lot of tight elements, but it was still fun.

My G meters are flipped for some reason, looks like I'll have to re-calibrate them. but I did hit 1.5G which is cool :-)

 

looks like epic fun! I wish we had Autocross here in Australia.. we only have Hillclimbs, nothing like that though!

 

Start one.

 

 

yep, we are a nanny state.......

that's why I will be setting the car up for Time Attack without the aero

 

I added rear camber to the back of the car (back up to a stock link on one side and a ronin "stage 1" on the other. It's at about ~1.8-1.9* in the back.

I took a bolt out of my camber plates to get the last little bit out of them that the bolt was blocking... it's up to -3.2* now. I might have to slot my struts to get a bit more up front.
camber plates slider was hitting the bolt head:



no more bolt head:


The car liked the camber... so that's good.

Nice photo of my car a fellow rx7 owner took (on a film camera no less, the actual photo looks much nicer, my scanner needs work...)



Video of yesterday's event. It was pretty quick... the rx7 needs more power. My main competitor showed up with new winter modifications (fresh 335 tires on all 4 corners of his 600 whp STI) and was much faster. I have to catch up to do :P I think it's finally time to start tuning E85.

 

Control arm things are happening

Started by removing the delrin bushings and cleaning off the undercoat? thats been on the S4 control arms I have since I got them...


angle grinders are the solution to everything:

 

 

Those are a little short now, Mike. Someone may ask you what a "nazda" is.

 

Egads Mike, what sort of nonsense are you getting into now???

 

Oh man are you going to do the Super Now spherical control arm bushings?

 

What an epic thread!!! Great job, that Mazda Rx-7 is a beast!

 

I was wondering when someone was going to figure it out yes.

Thanks!

 

Yeah buddy! We're still having some binding issues with the other delrin bushings?

 

I was never pleased with how they felt after they were clamped into the mount bracket... and bearings are always going to be better plus this will give me a bit more caster which is nice.

 

These are a lot of work to install

control arm fit in my drill press (barely) which was nice:



tapping to M12x1.25


pressed in new front bearings:



where the added caster comes from (and why you cut the arms):



done!

 

I see right now I'm just rolling with some poly bushings. I need to drive more to understand you awesome guys are feeling lol.

I knew these needed some work, but Jeezzzz that's a lot I hope it'll feel very nice once installed and hopefully help fix some of your turn in as well.

 

My wallet always feels way heavier after reading this thread... It's the weirdest thing........

 

 

Looking good! How does it feel with the new control arm bushings?

 

Those are pictures of the previous autocross. Next autocross on is on the 24th .

I haven't actually driven it yet since installing the bearings... but it's back on the ground.

 

 

The rear subframe link? I have a tcsportline link... Ground control also makes a nice one.
