So I knew it needed more front grip and less rear grip. So I changed the front and rear roll centers and the springs to get the handling I was looking for. Hope this helps a little.

That is my point too..thanks for the great information it is nice to have guys with experience like you to guide us.

Yeah, with a lipo and no weights, mine was 119g light. I did add weight for the race though.

Default RX8 pic

A few people have asked me to post a photo of where I am placing my weights. So to make it easy I cut and pasted this news item from my site.

Here is a photo of where we are placing our weights on the Xray RX8.
Picture shows YB-copper battery tray (75g) YB brass motor mounts (75g) 5 of the seven weights included in the YB universal brass round weight kit and an extra 20g round weight (60g). You can also see the YB stainless steel front and rear (mugen/offset) axles used with XRAY cvd bones. (these save a total of 10 grams off the rotating weight). Also the magnesium axle spacers (another two grams of the RM) and the hollow stainless steel midshaft (-5g off the RM).

We are currently in production on the brass and aluminum versions of the rear radio tray support.

I am a little bit confused by rx8 option parts ...they are so many...any suggestions whether is worth purchasing any of them?The car is so good out of the box and I do not know if changing parts will help its performance.

Thanks

It is easy..... How much are you away from the toplevel guys? If you can compete with them some rotating lightweight parts like aluminium CVD shafts can be usefull. If you are more than 0.5 sec a lap away you still have much to do without option parts, those parte will not make a difference larger than 0.1 sec.

Some parts like aluminium suspension arm brackets makes the car les fragile giving also less flex on the suspendion making it more stable. But hay, even the "plastic" MRX4-X is still a awesome and winning car so who needs all kind of aluminium parts?

There are different types of aftermarket parts. Some parts make the car heavier, like the YBSLOW goods, and we know that the RX8 needs some weight. Some make the car more reliable, such as being able to better withstand a crash and then you have the parts that make the car lighter such as rotating weight, and then there are some that are just money gobblers

Use some common sense and you will save money as well

Agree, I like plastic car, reliable. Better concentrate on some handling, get rid of the fancy stuffs.

Default Mod of flex radio plate

I'm thinking to mod the flex radio plate more smoothly, I've found that the plate design is simple and useful, but I feel its hard to flex smoothly. Unlike MRX5 or V8 11, those have the flex bearing going along the flex bracket and make the radio plate flex very smooth.

My feeling about RX8 flex design, its kinda hard to move when I press the radio plate side to side. Its totally harder than MRX5.

So anyone has the mod radio plate can share some mechical ideas for smoother flex mechanism. Appriciated

Its a crazy class, lightweight this, add weight that!! LOL..i ran 1/8 buggy for years,and miss the freedom of running my cars at full potential,i feel when u spend this kind of money, it should be as light or heavy as YOU want it to be,i love the class but think that's kinda INSANE,,, how cool would it be if we could use them at there full potential, as light and fast as they can run for your well spend/hard earned money..i mean u buy a 900 engine, just to counter all the weight you have to put back on? errr , it would be so much more affordable if u ask me, have like the old school rules i remember was to have, GTP class, and OPEN 1/8 <edison N.J.>..and let the rest sort it out.. that being said..

my car is perfect, without a single hop up...even tho i have a bag of new goodies to test and play with.. the car in my honest opinion, IS that good. Leave it alone, unless u need to add weight, the whole reason for my rant...sorry.. my car feels perfect, if you think you need to do something here or there to improve it, there are plenty of "options" to do so
