Anyone using this lower control arm set-up on their RX7. I am thinking of replacing my stock suspension bushings with poly, then came across this set-up; would allow for more tuning of the front end. My car is not a daily driver (about 8K year) but gets used a lot for autox and time trial events, I am not too concerned about "cheating" the rules since in the classes I run in a standard port RX7 is not the running for a victory. I just would to improve my car for track driving enjoyment, starting to improve my on track skills so starting to feel the need to improve suspension. Hoping this would allow for better camber set-up than camber plates. Concern is noise when I am driving on the street.

If this info below helps giving guidance (my current set-up);

Currently run Koni's all around with RB springs, big ST front sway bar, stock rear sway bar (for now, might remove), replacing rear end bushings with Mazda OEM bushings before season. Tires 195/50/15 front, 225/45/15 rear all Hankook RS4s. Either front poly bushings or this set-up is the main question. Non coil-over car.

 

I don't have personal experience with those, but if your concerned with noise, which will probably be present with all those heim joints you may want to consider the adjustable control arms from Racing Beat. A friend of mine is running them and is very pleased.

in for other people's responses. Thinking about running these T3 lower control arms as well.

 

I am running the Techno Toy LCA's and tension rods. I have nothing but great things to say about them. They replaced my OEM suspension hardware and made a huge difference to the cars driving experience, and are fully rebuildable when (if) the time comes... just pop in a new ball joint.

I do not really notice any noise or very harsh road feedback that would be related to the solid rod ends. You can feel slightly more 'road' through the car but no more of drastic a change then what you would get going to a lower profile performance tire for example.

All the T3 hardware is top notch quality with great customer service. We are lucky to have them developing parts for our car. Ignore some of the haters haha.

I have a GSL-SE rear axle I will be installing with their lower adjustable rear links complimented by all new OEM upper links and watts link hardware. Also waiting for details on their brake kit that is in development...

I think the GTX2 design is perhaps more adjustable than the version I have, Tyler at T3 could go over the pros and cons.

Talked to guy named Bryan at T3 for about 20 minutes about options and differences between set-ups they offered. I was pretty impressed with the depth of knowledge he had with their products and understanding of 1st Gen front suspensions. I did not ask or discuss the rear suspension set-ups; TBO do not want to mod the rear suspension of car to run anymore than I currently have planned. Like the thought of increased track width, better camber settings, and better control under heavy braking that this front set-up appears to offer. Thank you for your input.

 

What did he recommend as far as trade-offs between their two lower control arm options?

 

Main difference is that using just control arms, you could build up from there. i.e. start with stock TC rods and then upgrade at later date. There is more adjustability in the full kit option and it uses a more upgraded ball joint from the standard T3 control arm (which uses an AE86 ball joint which is an upgrade from RX7 OEM ball joint). Probably best to just call T3 for really detailed questions. RB makes an upgraded control arm also but believe it is more expensive.

 

The stock ball joint is a little small but I've only had one fail where it came a little loose in the control arm and rattled, handling was a little off. Potential big safety problem. That ball joint had a long hard life. The T3 part looks quite nice.

 

I have also been thinking about these and have heard nothing but good things about them. Anyone have any install pictures? I know the turn around time for some of the parts they offer is a week or two, not bad for someone who is actually making quality parts for the 1st gens.

 

When I ordered my control arms, tension rods and rear trailing links I had the parts in about 2-1/2 weeks. When I ordered my coil overs it took 4 months turn-around. I think it just depends on whether they have it on a shelf, or have to fab it.

 

These look awesome. I've been thinking about replacing all of the bushings in the car, and may look into the T3 when the time comes. I have ReSpeed coilovers and Konis up front now.

 

Are you running the OEM style or the GTX2's?

 

Just received my GTX2 parts this week! Will hopefully start the install this weekend. Still in the process of removing stubborn tie rods and pittman arms.

 

I am running the OEM style.

For the ball joints what kind of removal tool are you using? I had really good luck with the typical spreader just had to tighten the crap out of the bolt until it went bang and flew apart. Leave the ball joint nut on the last few threads so parts don't fly around.

On the topic of Techno Toy, they are putting their FB Rx7 Wilwood front brake kit on their website this monday.. Looks like it will run new hubs and aftermarket rotors.

 

I used heat, a hammer and one good smack. I noticed the kit, it looks good for the price.
