I have a 2k 5 speed. I got almost 93k miles with original cluch. I use red line mt 90 since 20k miles. Lately, I've been having problem shifting. I have to really push the ****ler into gears. Yesterday, I was driving with radio off and I was hearing ruttle in 1st gear at load speeds. Sounded like a diesel engine. Do you think it's time for new cluch? If yes, any suggestion? ACT maybe?
Thanks in advance
