Yellow springs look a LOT like white springs when the yellow dot wears off. It wouldn't have been quite so bad if I didn't have one of each up front.

tsk... do the quick spring check, always...
Take one spring of known rate, place it against another spring, and squeeze between fingers.
If they both compress to the same amount, same rate, if one compresses less than the other they are different!
Have to do this regularly as my HPI Pink's and Blues are black wire jobs with no markings!!

and how long have you been running it like that? spill the beans...

Yeah, HPI Springs, not the Hara's. I ony rarely use the blue's and gold, could probably get away with 2x silver, 1x blue, 1x pink. Does depend on track conditions though.

Invest in some paint pens and make some nice markings on the springs.

And yes, how long did you run bolloxed up front springs

I'm not sure to be honest. It's possible they've been that way since I built the kit. I pretty much always go with white/blue on carpet. The yellow dot on this particular one was almost invisible, and right at the end of the spring. So there's a chance it was like that since I built the car before snowbirds. It's actually been great at home the past few weeks, but dreadful everywhere else.

There's gonna be a lot of fast guys at our track this week for our end of season race. We'll be on LiveRC under CORRC if you want to watch failure happen live and direct from the rug in Denver.

Hi.

It is easy to see the difference between the springs as they have different turns. Smooth springs have many turns and hard springs have lees turns. I have made a list with the HPI and Tamiya springs. I have alse added block settings and gearing. See attachment.

It is in Danish, but "Omdrejninger" means turns. Use it if you want.

No they're not, unless you don't know how to type "HPI spring colors" into Google.

At any rate, here you go (under the Pro4 section):

Some other springs you may like to consider are the Xray springs... 2.6 and 2.8 rating.
I run on generally low to medium grip ashpalt and carry a full set of Hara's, the HPI Blue, Silver, & Purple springs. The Xray & HPI are linear where as the Hara's are not. They can feel a bit peculiar on some track but on others they are the Gold/Best!....

The G/diff's can leak! Try not to over tighten the screws as this will warp the housing and leak worse. I'm also trying Assoiciated Green Slim around the O-ring seals and housing gasket.
