Man, I'm in the Navy and made some dumbass choices when I was young...because...well...that's what a lot of us do. Then, I started learning from the dumb **** I was doing. Long story short, "saving" money is all cool in theory, but it's about HOW you SPEND your money that leads to the saving. Once you get that, you're good.
Tip #1 - Learn how to cook.
Tip #2 - Used parts are not always bad parts. SoldMySS mentioned some good things, so you could try to find, like, the tires USED somewhere, plus other things. I'm always seeing
suspension pieces up for sale all over. Make sure the used pieces are in good shape, though. Looking around for deals is going to take some patience, and young people don't always have it.
However, exert some will and look around for good deals. They're out there...just have to find them. Trust me, searching can be part of the "fun".
An example: MAN, I needed to ditch these ****ty street tires for when I headed out to the road course. They were holding me back like a mofo. However, there was NO WAY I could convince my wife to let me buy a brand new dedicated wheel/tire setup, AND she was pregnant at the time. A buddy of mine I met at a track event mentioned to me a set of "scrubs" for tires. I was like, "WTF is that?" Scrubs are BARELY USED sets of tires that might still have plenty of life left in them. Best part is they cost a fraction of the new price. I found a set of rebadged Hoosier racing slicks at Bimmerworld for $75 a pop. That's friggin' excellent when you consider that brand new they can run as high as $400 a piece! This set I picked up had ONLY 2 practice laps on them!
And then! Just by showing a little patience, I found a BRAND NEW set of Steeda Q1S wheels for almost half the price. Brand new.
There you go. Dedicated track setup.
All I'm saying is...just look around, my man. Have some fun doing it. You'll find some **** out there top grade, discounted.
