Finished building my car and after almost 6 years roughly away from the sport will be racing the car next Sunday for the first time.
It have a question regarding springs, I built the car with the stock springs but they feel really soft. I will be running a fast track and was wondering what a good front and rear spring would be. The 418 kit I have came with a few other tamiya spring options and when I bought it it came with RIDE black extra hard 0.333kgf/mm and purple hard 0.316kgf/mm springs. Anyone know what would be the best starting option?
