Terrible. What a let down. I have experienced F1 Race Factory several times and Speedstreet is definitely not as nice as F1. Not even close. I bought 3 Speedstreet races through LivingSocial. I bought the deal because I enjoy gokarting and the location was closer to my friend's house, who lives all the way up in SunCity/Peoria, but it's a farther drive for me than F1.
First, Speedstreet would only let me use one race voucher that day. Sigh, now I have to make 2 other special trips to use the other vouchers. Second, the karts are in terrible condition; chunks of plastic missing, unresponsive pedals, and torn-up/ripped safety belts. The track itself is fairly nice but I couldn't enjoy it due to the unresponsive acceleration; I kept having to mash the accelerator in just the right place to get the vehicle to move. Third, the helmets are not stored in any size order and they're not labeled so I had to try on 3 different helmets before I found one that sort-of fit. Clearly, safety is not a concern for Speedstreet. Also, another difference is that Speedstreet do not keep their karts running/warmed up, so it takes a few pulls to get them going. F1 gets enough business and wants their customers to get-n-go asap so they keep the karts running. Speedstreet took 2min past the start-time to get my kart going. Ugh.
I would never go again and would not recommend it.
