Can you tell us more about your spring kit? I'm assuming is Swift springs.

 

Looks nice. Definitely some of the upgrades I'm interested in doing. Question, any reason the client didn't do the over axle pipe to replace the non-functional OPF?

 

Just saw this post as I'm talking to a local shop to have it installed. In the features, it says "Minimal effect on seat travel to accommodate taller drivers." What does this really mean? I've had shops say that there is no loss of leg room. My seat is all the way back and all the way down (LWB).

Thanks,
matt

 

Unfortunately the Akrapovic over axle pipes are no longer available.


Yes, we use Swift Springs and we can share more details if you give us a call at 714 843 0200 or email sales@bbiautosport.com

The horizontal bar behind the seat impedes the seat travel so you will lose about 2 inches or so.

 

This is really great to know beforehand. While I'm disappointed because I really like your bar, I'd rather know now. Two inches is just too much to give up. Thanks!

 

Matt, Here are good pictures to show where the bar meets the back of the seat. There is no way to get around it

Understand that we might be fighting physics. But, it would be like getting the perfect position and then strapping 2" blocks on all the pedals. Thanks again!

 

Just wanted to give an update.

I did have the BBi bar and anti-submarine bars installed after testing it out in another car. The great news for tall folks like me is that with the fixed carbon buckets, you can move the seat all the way back and down with no loss. BBi, I appreciate your honesty and conservative estimate about travel loss but it appears to be a non-issue. Huge relief and very happy with the bar.

Thanks!

 

Hi Matt! Thank you very much for chiming in to share about the your experience with our bar!!! Did you happen to purchase it from SP Motorsport?
