The RMM will definitely help with drivability and fits within your budget constraints. Follow-up with a tune when finances permit.
I could spend more
I just got my yearly bonus, but I was looking at spreading the money around to different things.
House, family, savings and hobby
300 seemed fair for a first mod purchase but it seems I may have set the bar too low.
In the past I have always lowered and mud flapped my evos.
So it looks like I will just be ordering some rally armors the lower sides of my car are filthy and spend the rest on MP Thundercracker or maybe some swift spec r's if I'm feelin frisky
