Do not think you do need those parts to go faster, you won't go any faster.....
Roelof,
Well, I run in the Southwest series championship here in Texas. It does get hot here for the summer races which is most of them. 95 deg. F to 105 Deg. F is not unusual. Last month at our SWS race here in Houston you could actually see the mugen's sag on their suspension arms by 2mm from early
morning to the very hot afternoon. That is why I was interested in the stiffer plastic.

I teamed up with Mike Quellar in 1990. We ran BMT 891's that year in the SWS races. We were the first to run BMT's in the US in 1990. We were directly supported by BMT. Mike won the SWS championship that year in 4 wheel drive, I won the Two wheeled drive class that year. I ran a pre-production 891 Austin car almost identical to the one Collari won the race with in the 1991 Worlds at Austin (Hence the "Austin" label"). Of course I finished around 91st out of 150 entries at the 91 Worlds. Perhaps Collari was a little better driver than me!!! The BMT 891 is my favorite all-time car.

Yes, then it can make a small change if the standard plastics become that weak in the hot sun.

I have driven the BMT Active and the Active 95R, I also do like the BMT car, my favorite is the 95R. It was stable, easy to maintain, very cheap over 1 year racing because the strength of the used materials and even when the setup is far out of balance it is easy and stable to drive and at the same time you can drive it very agrassive.
In my M18 I have created the active rear suspension and it is awesome to drive.

Remove the spring and the collar from the brake rod it is not needed. Keep in mind that only the rear wheels do the braking. If the brakes lock up the rear axle the car will spin out if it's at speed.
Use the end point adjustment for the brake side to limit the throw of the servo arm to a comfortable level. This will change with changing grip and layouts of different tracks etc. Use the knob to compensate for pad wear.

Turn the ABS off and use your endpoint adjustment to control brake power.

If I do that then the car drifts because the back wheels lockup!!!!
If I mess with the endpoint I can not get it to the point where it is not so hard. Then I lose it

Try to use instead of the fueltube as a spring a real spring like the one on the throttle link.

Will this spring be just what I need, Is it soft but hard enough to pull the brake.

If it is easy to lockup the rear wheels without finding a sweet point with the transmitter EPA setting you have to create a softer spring

Check your expotential on your radio. If this is turned up, no matter how you set the brakes they will lock up.
Some radios call it expotential, some call it push. Go to the brake mode in you radio and see how it is identified.
If you dont have enough exp. or push, the brake will not work at all.
Try and set the exp. at around 10 to 15 points and then adjust the end point for the brake.

If they lock up at speed, back off the endpoint until it stops locking up. You will never have the kind of stop on a dime brakes of a tc with a front diff or spool.

Set the way I like, they will still lock up at slow speeds, like pit lane or really slow corners so a little care is needed in those circumstances but at speed, they wont lock.

Depends on the track.

Just noticed you are on Marco Island. That's where I stay for the Winternats, my mother has a place there.
