Ordered a Reedy 13.5T and XR10 Pro combo at 11pm Thursday. It was at my door Friday morning. Ran TQ at Saturday's club race. Throttle is the only place I order from now.

Finally a store that actually stocks what's on the site. No backorders, no 'ships in 2 weeks.' I've been burned by other shops too many times. Throttle has been 100% on 11 orders.

The tire compound guide is genuinely useful. I switched from M3 to M4 on our hardpack outdoor track and immediately dropped 3 tenths. The recommendation was spot on.

Built my first portal-axle crawler using the chassis filter. Every part was compatible. Zero wasted purchases. That tool alone is worth bookmarking the site.

The dyno charts aren't marketing fluff — they match what I see on track. My 5.5T runs exactly as hot as the chart predicted. I now use Throttle as my pre-purchase research tool.

I've been racing for 12 years and this is the first online shop that stocks titanium turnbuckles for the B6.4 without me having to call ahead. Incredible inventory.

Free shipping kicked in at $49. My order was $48.50. I added a set of body clips and saved $8 in shipping. The progress bar in the cart is genius — I always end up adding something.

Switched to Throttle after my old shop closed. The 'Build Your Setup' filter showed me everything compatible with my XRAY. Spent 20 minutes, built a full race setup. No guesswork.
