You'll still need speedboost to buy bodykits, old bodkits for S15/Corolla that cost 4k $ I've bought an old one for 1500 speedboost

Cheaper

I'll help you a little, when you change the car, change it to TTRS10

You'll find Z4 bodykit (BMWM3E92 for the widebodykit one) S15, Toyota Supra, Corolla, GTR, GT-R 34 old bodykits and much cooler

1500 it's pretty good deal
